The quick overview? The Republicans take a statistically significant lead.
It has been a while since I have posted an update, so let's give every state that El (the SanityIID model) is following.
In Alaska, El is still screaming a warning about a lack of data. There just isn't enough polling happening in Alaska for a race that appears to be this close. Still, the recent polls are all going in Sullivan's (R) favor. The long term probability for a Republican win in Alaska is now at 65%. Expect this percentage to continue to rise unless Begich (D) starts getting better polling numbers.
The new polling in Arkansas shows that the state is slipping more firmly into Cotton's (R) hand. Current long term estimates show Cotton with an 81% chance of winning the state.
Colorado appears to be leaning Republican with Gardner (R) having a 65% long term chance of taking the state. Udall (D) has slipped behind and the race seems to be stabilizing in the Republican's favor.
Georgia seems to be leaning toward the Republican's as well. The lastest polls show Perdue (R) with a 77% probability of taking the state over the long term. Nunn (D) has been consistently falling behind in the polling. If upcoming polls don't any increase for Nunn, expect the probability of Perdue to win to increase over time.
Democrats are losing ground in Iowa as well. Ernst (R) currently has a 71% long term chance of taking the state. While the mid term and short term chances are a little less stable, they are all still showing strong support for Ernst (R) over Braley (D).
The Independent candidate, Orman (I), is still showing well in Kansas. There have been a few recent polls that are startling in their sudden change, but the long term chances are still showing solidly for Orman (I) over Roberts (R). We will have to wait and see whether the most recent polls in Kansas are outliers or whether they are the start of a comeback for Roberts.
Long term predictions for Kentucky are showing McConnell (R) with a commanding lead over Grimes (D). The long term predictions show McConnell (R) with an 86% chance of winning the election. The short and mid term predictions aren't quite as rosy for McConnell, but they still show him with a solid lead.
Louisiana? Republican. Virtually all polls have been favoring Cassidy (R) over Landrieu (D). While El does give a data warning for not enough polling, there is still a 78% long term chance of a Republican victory in Louisiana. The mid and short term probabilities only increase for the Republicans.
Michigan is the first good news story for the Democrats. Long term, Peters (D) has an incredible lead over Land (R). The long term probability of Peters winning is pegged at the limit of El's accuracy. It is also reported in the news that the Republican's are going to pull their television commercials in favor of spending that money on more competitive races. While there will always be a statistical possibility that Land (R) could win, the chances are very, very small indeed.
New Hampshire also looks good for the Democrats. Shaheen (D) is still holding a stable lead over Brown (R). Long term, the Republicans only have a 23% chance of having New Hampshire in their column.
And finally, the last state that the El model is following: North Carolina. North Carolina is another spot that looks good for Democrats. While the polling is close, it is also stable. Not a single poll is showing in the Republicans' favor. Hagan (D) is leading Tillis (R) by a margin that pegs the model in the Democrats' favor. The only clouds on the horizon is that it wouldn't take much of a change to begin dramatically swinging North Carolina toward the Republicans.
