I’m ordinarily not a big believer in “game changes;” they may be good at selling superficial books about presidential elections, but if you actually drill down into, say, the polling data from the 2012election, all of those supposed “game changes” barely moved the needle at all when they happened. But we may have had a genuinely game changing event on Wednesday, in a previously sleepy race that was on few people’s radars as competitive; it changed not only the trajectory of one race, but the overall likelihood of Democratic control of the Senate.On Wednesday, the Democratic nominee in the Kansas Senate race, little-known and underfunded Shawnee Co. District Attorney Chad Taylor, pulled the plug on his candidacy right before the deadline. Now ordinarily, you’d think that would reduce Democratic odds in Kansas from almost zero (5 percent, according to our model on Wednesday) to absolute zero. That’s not the case at all, though. There is also a much better-funded and more appealing independent candidate in the race who might caucus with the Democrats if he wins: Greg Orman. Taylor and Orman were splitting the vote against the Republican three-term incumbent, Pat Roberts, who was already weakened by a mediocre primary win over Milton Wolf and accusations that he doesn’t actually reside in Kansas.Previous polls of a three-way race showed Taylor and Orman, added together, outpolling Roberts … but combined vote shares are of no value in a first-past-the-post system. However, the most recent Public Policy Polling look at Kansas tried out permutations with just Taylor vs. Roberts, and Orman vs. Roberts. Roberts would beat Taylor 43-39, but Orman (thanks to crossover votes from moderate Republicans) would beat Roberts 43-33. (In a three-way race, it was Roberts 32, Taylor 25, and Orman 23.) And in a remarkable bit of team-player-dom, Taylor seems to have taken those polling results to heart and pulled the plug on his sputtering campaign.Put visually, here’s the trendline from the old version of the Kansas race:
And here’s the trendline from the new version, as of Wednesday:
The switch to a two-way race between Roberts and Orman, where Orman has a 10-point lead, dramatically changes the trajectory of the Kansas race. Where the Democrats previously had a 5 percent shot of winning the race, they now have a 54 percent shot!That same shift also has a big impact on the overall Senate picture, suddenly making the Democrats more likely than not to retain control of the Senate. In our last full-length look at the Poll Explorerlast Thursday, Democratic odds of retaining the Senate were 45 percent, and it had stayed parked there at 45 for most of the week, ticking up to 46 percent on Wednesday. However, the Kansas news boosts Democratic odds of controlling the Senate up to 56 percent overall.
Why such a big boost? Last week, I’d used the analogy of a plate-spinning contest. Although the Democrats had enough races, where they had even odds or better, to enable them to hold 50 seats (which would give them control, thanks to Joe Biden’s tiebreaking vote), they were spinning a lot more wobbly plates than the Republicans. If only one of those plates fell, they’d lose the whole game. Well, with the Kansas news, the Republicans have essentially been handed their own wobbly plate. The Kansas race is still hardly a sure thing, in itself, but it gives the Democrats a much bigger cushion against failure somewhere else.
Shouldn’t a 10-point lead, though (which would be considered to be outside the margin of error) give Orman better odds than 54 percent, though? There’s a whole other wrinkle to the Orman candidacy, which we’ll explain further over the fold:
While the shift from 5 percent odds to 54 percent odds is a huge jump anyway, it would be much higher if Orman were to simply confirm he would caucus with the Democrats. On the surface, it’s a reasonable assumption that he’d caucus with the Democrats. Orman ran for the Senate in the Democratic primary in 2008, and his issues page — where he says, in rather oblique fashion, that he’s pro-choice and supports immigration reform — makes it clear he’d be very uncomfortable as a Republican.However, Orman isn’t saying that. (Nor would it be wise for him to do so; he’d probably shed a number of moderate Republican votes as soon as he put on a blue shirt, in a state where he can’t afford to lose any of those votes.) Instead, he tiptoes around the issue, saying that he’d seek to work with “work with the other independent Senators to caucus with the party that is most willing to face our country’s difficult problems head on and advance our problem-solving, non-partisan agenda.” But more importantly, he also says:
With that said, if one party is clearly in the majority, he will seek to caucus with the party that was in the majority as that would be in the best interest for the state of Kansas.
Here’s where the modeling gets tricky, and it starts to cross over from mere poll aggregation into game theory. In order for the Democrats to “win” the Kansas race, they have to not only see Orman defeat Roberts, but they also have to garner a majority of the other seats anyway. If Orman wins, but the Republicans already have a majority with or without Orman, then Orman just caucuses with the Republicans anyway, and the Democrats have “lost” that race too. In other words, here are the potential scenarios:
Democrats win 48 seats, Republicans win 51 seats: Orman caucuses with the Republicans, pushing that total to 48 D, 52 R.Democrats win 50 seats, Republicans wins 49 seats: The Democrats will have a majority anyway because of Joe Biden’s tiebreaking vote, so Orman caucuses with the Democrats, pushing that total to 51 D, 49 R.
Democrats win 51 seats, Republicans win 48 seats: Orman caucuses with the Democrats, pushing that total to 52 D, 48 R.
Democrats win 49 seats, Republicans win 50 seats: Here’s where the real uncertainty enters the picture. There’s no “clear” majority (in other words, if Orman throws in with the Democrats, the Dems will have a majority because of Biden; if he throws in with the Republicans; the Republicans will have a majority), and Orman needs to go one way or the other, unless fellow indie Angus King decides to leave the Dem caucus and join Orman on a two-person magical unicorn ride. Our model, awesome as it is, still can’t predict Orman’s state of mind, so in all 49 D/50 R scenarios, we’re allowing Orman a 50 percent chance of caucusing with the Dems and 50 percent chance of caucusing with the GOP.
So that’s why Democratic odds of “winning” the race are 54 percent, even though Orman’s personal odds of winning the race are much higher. In all scenarios where the GOP ends up with 51 seats or more regardless of what happens in Kansas, and half of the ones where they end up with 50, an Orman win just pads the Republican total further.And that’s why our histogram no longer resembles a neat, tidy bell curve any more (if you want to see what it looked like, check our post from last week). Scenarios where the Democrats win exactly 50 seats, which used to be the modal result, are now pretty rare, now mostly involving permutations where Roberts wins the race instead. Most of those 50-seat scenarios instead get turned into 51-seat scenarios, since at that point Orman gets turned into a bonus Dem. Fifty-one seats is the new mode, while fifty seats is the new median. Either 50 or 51 is enough for control, so now the Democrats retain control in the majority of all Monte Carlo simulations.
While Kansas is largely responsible for the Dems’ move upward, if you look at the totem pole, you’ll also notice that Mary Landrieu’s odds in Louisiana have increased significantly (perhaps too much to be truly realistic, from 47 percent to 76 percent). That’s thanks to one poll that didn’t attract much attention, a poll released by the Senate Conservatives Fund that had Landrieu leading her likely runoff opponent, Republican Bill Cassidy, 49-43. Why, you might be asking, would a right-wing group leak a poll showing a Republican in such dire straits? Well, it was to show that their preferred candidate, Rob Maness, trailed Landrieu by slightly less (48-44), as well as improving his share in the jungle primary. Whatever their purposes, though, the model counts it as something of an own-goal, boosting Landrieu’s averages even further because it’s a Republican partisan poll and the model downweights Cassidy even further!
In addition, two polls that put Michelle Nunn in a small lead (after a long series of ones showing her losing) boosted her odds somewhat, from 14 percent last week up to 23 percent now. That’s balanced, however, by several polls in Kentucky showing Mitch McConnell expanding his lead a bit, moving Alison Lundergan Grimes’s odds there from 22 percent down to 18 percent.
Let me repeat these caveats until I’m blue in the face: As happy as this shift made me, the fact that the Democrats have a 56 percent chance of controlling the Senate this week is in no way a prediction that they will control the Senate, any more than, when we were talking about this last week, the fact that the Democrats had a 45 percent chance of controlling the Senate was a prediction that they will lose the Senate. The overall proposition is still, entirely, a coin flip. The coin has simply gone from being very slightly weighted in one direction to very slightly weighted in the other direction.Finally, let’s take a look at the gubernatorial races. For one brief day, the median number of Dem-held state houses ticked up to 23, which would be a two-seat improvement over what they currently have. However, that ticked back down to 22 today, which is a one-seat gain. That’s largely due to polling fluctuations in Florida, where a SurveyUSA poll on Tuesday gave Charlie Crist a 45-43 lead, but then a Univ. of Florida poll on Wednesday gave Rick Scott a 41-36 lead.
Overall Democratic odds of gaining gubernatorial seats continued to move up, though; it was at 52 percent last week, and now it’s up to a 60 percent chance. That’s in part due to improved odds in Georgia and Arkansas (which the Democratic candidates are still on track to lose, though), but more than anything due to Alaska, where there was an entirely separate switcheroo in a three-way race where the Dem and indie had been splitting the anti-incumbent vote.
There, Democratic nominee Byron Mallott dropped out to become the Lt. Governor on a ticket with independent candidate Bill Walker. What few polls we’d previously seen of a head-to-head matchup between Walker and GOP incumbent Sean Parnell showed a very close race, and even a Walker lead in one case, so that boosted Dem odds here from 1 percent to 37 percent. (To make things simpler, we’re counting Walker as a de facto Democrat here, since policy-wise he’d be a big improvement on Parnell, even though there will be an “I” next to his name; there’s no need to ask about who he’s going to caucus with, seeing as how governors don’t caucus with anybody, so Walker’s individual odds are what’s important.)
We’ll be continuing to post updates like this several times a week, as we see if the Democrats can keep building on this momentum or not.
