Most Democratic incumbents and challengers in battleground Senate races raised more than opponents during the last three months of 2023 and had bigger bankrolls at the start of the year, new filings with the Federal Election Commission show.
Some races are still taking shape, however. In Wisconsin, Democratic incumbent Sen. Tammy Baldwin is effectively unchallenged, but that could change soon.
Pennsylvania Sen. Bob Casey was outraised by his likely Republican opponent but had more money on hand on Dec. 31. But like other endangered Democrats, Casey’s opponent has already put $1 million of his own money into the race and is expected to spend more. Outside committees also can be expected to layer more millions on top of what candidates spend, though they also pay much higher rates for TV advertising so the money doesn’t go as far.
