Below are poll averages (from Real Clear Politics) for Gubernatorial, Senate, and contested House seats. A positive poll average favors the Republican candidate whereas a negative poll average favors the Democratic candidate. From the poll averages a ranking and probability are calculated for each race. A probability above 0.5 (50%) favors the Republican candidate whereas a probability under 0.5 favors the Democratic candidate. The higher ranking, the higher the probability the race will go to the Republican candidate. The lower the ranking, the higher the probability the race will go to the Democratic candidate. Since polling in House races are not very accurate, the formula to calculate the probability is more complex taking into account race ratings by the Cook, Election Projection, and Sabato political reports as well as generic congressional polling results and PVI (Partisan Voting Index). A positive PVI means the percentage of registered Republicans in the district outnumbers registered Democrats whereas a negative PVI means the percentage of registered Democrats in the district outnumbers registered Republicans. The overall probability for the President, Senate, Gubernatorial, and House races are computed to project the number of seats (including the presidency) that are going to be won by Republicans and Democrats respectively. Race candidates will be filled in to the below tables once they are determined by state primaries. I will update and post this information regularly (many primaries and candidates have not been decided and most polls are not pertinent because they do not contain the right candidates). Below is an overall summary of the predicted outcomes based on probability density function models.

Governor Races: Current - Republicans 29; Democrats 21 (including 2 Independents); Model Projection - Republicans 28; Democrats 22 (including 2 Independents)
Senate Races: Current - Republicans 45; Democrats 55 (Including 2 Independents); Model Projection - Republicans 51; Democrats 49 (Including 2 Independents)
House Races: Current - Republicans 234; Democrats 204; Model Projection: Republicans 250; Democrats 188
Below is an overall summary of the predicted outcomes based solely on election polls:
Governor Races: Republicans 27; Democrats 23 (including 2 Independents)
Senate Races: Republicans 52; Democrats 48 (Including 3 Independents)
House Races: Republicans 247; Democrats 191
Looks like republicans did way better than expected but that would have been hard to predict from the polls. A lot of them were way off, thankfully!
