(We calculate our weekly approval ratings using an average of the two pollsters who conduct weekly approval rating polls: Reuters/Ipsos and You Gov/Economist. This provides consistent and accurate trending information and does not muddy the waters by including infrequent pollsters. These two pollsters tend most often to be middle-of-the-road relative to Rasmussen, who does a daily poll, and Gallup, who announced they will no longer do a weekly poll after 2018. Both Rasmussen and Gallup tend, at times, to be outliers.)

Trump's approval rating, already historically low at the outset of his presidency in January, 2017, has declined since then to 44%; his disapproval score has increased markedly, from 44% to 55%, and thus his "net" score has decreased from +3 to -11, a change of -14. He has yet to achieve the 50% approval mark in any single week in his entire presidency.

To gain control of the Senate, assuming a Biden win, the Democrats need to a net +3 seats assuming Biden wins, to get from their 47 current caucus seats to 50, or a net +4 if Trump wins (though one can assume that if Trump wins, it is highly unlikely the Dems will be winning enough close Senate races).

The Generic Congressional Ballot is an average of all recent "generic ballot" polls in which respondents are asked if they would vote for a Democrat or Republican as their representative (with no names) if the election were held that day. The most recent generic ballot polls show the Democrats with a substantial +7 point advantage.

Using our exclusive BTRTN House Prediction Model, using generic ballot data and adjusted for campaign-specific polling and other factors, the Democrats stand to pick up an additional +17 seats (give or take a few) in 2020. The Democrats are a virtual lock to maintain control of the House; we peg it at 99%.
