In Maine, Republican Susan Collins is in the middle of the most difficult Senate race of her career. Her personal and job approval ratings continue to deteriorate, and her advantage in ballot tests against Democratic state House Speaker Sara Gideon is slipping as well. Collins has disposed of credible candidates in the past, but this race will be more challenging. The Maine Senate race is now rated a Toss-up from Tilts Republican.

The New Hampshire Senate race is now rated Solid Democratic after having been Likely Democratic, leaving Republicans defending 10 of the 12 most competitive Senate seats in the country. That discrepancy is part of the reason why Democrats are within striking distance of the net gain of four seats they need for a majority. Democrats could also control the Senate by gaining three seats and winning the presidential race.

Even though Hillary Clinton carried the Granite State by less than one half of 1 percentage point in 2016, there’s little indication Democratic Sen. Jeanne Shaheen is in all that much trouble. Republicans have struggled to find a credible challenger to the senior senator, and even if they do unearth someone, there would still be a September primary, which would leave little time for the GOP to focus on Shaheen. Republicans would need Trump to win New Hampshire by a convincing margin to defeat her.

With seven months to go before Election Day, there’s still time for the races and the fight for the Senate to develop, particularly when it could be the beginning stages of a global crisis. Even if voters don’t blame Trump for the pandemic or fault his response, a weak economy would leave independent voters without a reason to overlook the president’s tweets and personal style. That would make it more difficult for Trump to recreate his 2016 victory and put pressure on GOP senators who need to outrun the president to win reelection.
