Some of Democrats’ once-hateable figures are out of the picture. And emerging democratic socialists haven’t made for strong lines of attack nationwide.

Republicans have tried to find a new boogeyman this year as they rail against Democratic socialism and the “radical” left: Zohran Mamdani. Alexandria Ocasio-Cortez. Bernie Sanders.

Still more mentioned than all of them, at least in campaign ads: former President Joe Biden.

A POLITICO review of hundreds of ads running in battleground House and Senate races in recent months shows Republicans largely haven’t seized on progressive icons in paid media. Instead, Biden is the Democrat most likely to be mentioned in GOP ads this cycle, coming up across dozens of races.
