Democrats see an expanded path to the Senate majority as candidates become competitive in 10 states that President Donald Trump won by double digits in 2024: Ohio, Alaska, Iowa, Texas, Florida, Kansas, Nebraska, Mississippi, South Carolina and Kentucky. Republicans hold a 53-47 majority and began the cycle with a favorable map, but Democrats must defend two seats in states Trump carried and capture four Republican-held seats, including at least two in double-digit Trump states. The shift is most pronounced in traditionally Republican states, although Georgia and North Carolina are also competitive. Kentucky Democrat Charles Booker is within single digits of US Representative Andy Barr in internal polling, while Barr has a $2 million cash advantage. Democrats say Kentucky Governor Andy Beshear, who has endorsed Booker, could help the campaign. Republicans continue to lead spending in several expansion states, while President Donald Trump's approval rating has fallen to 32%, according to a Reuters/Ipsos poll. Analysts say the number of competitive races could force both parties to redirect resources during the final weeks before Election Day.
