Biden announced he will visit the states while polling shows the Senate races are tightening. In Pennsylvania, radical Lt. Gov. John Fetterman (D) is leading Trump-endorsed Dr. Mehmet Oz (R) by about 5 points. Polling is a bit tighter in Wisconsin, where radical Lt. Gov. Mandela Barnes is leading Sen. Ron Johnson (R-WI) by 2 points.

Biden’s appearance in both states may not benefit Fetterman or Barnes. Biden’s polling among Pennsylvania voters is 17 points underwater (37 approve – 54 disapprove). Among Wisconsin voters, Biden’s approval rating is 15 points underwater (39 approve – 54 disapprove).

While Fetterman has agreed to campaign with Biden on Labor Day, he will reportedly not meet with Biden on Tuesday, the president’s first of two visits to the state in a week. It is unclear if Barnes will meet with Biden in Wisconsin. Biden’s underwater polling in both states is likely a deterring factor for both campaigns.
