The 10 Senate seats most likely to flip in 2022
CNN
(CNN)The midterm elections are still 18 months away, but the fight for control of the Senate is already shaping what gets done in the nation's capital this year.
In an evenly divided Senate, where Vice President Kamala Harris gives Democrats the tie-breaking vote, every vote matters. That's proven to be a crucial consideration for President Joe Biden as he tried to pass his Covid-19 relief plan and now his infrastructure and jobs proposals.
Looking ahead to next year, that means every Senate race matters. Republicans only need to flip one seat to take back the majority, while Democrats are eager to cushion their majority by picking off a few more seats currently held by GOP senators.
Democrats' best opportunity to do that is in Pennsylvania, which CNN ranks the seat most likely to flip partisan control for the third month in a row. The top 10 Senate seats most likely to flip are based on CNN's reporting and fundraising data, as well as historical data about how states and candidates have performed. As the cycle heats up, polling and advertising spending data will also become factors. Our ranking first published in March and was updated in April.
