Ads have been released that show four Democratic Senate candidates in battleground states either working with former President Donald Trump or agreeing with his messaging as the November election is less than a month away.

Campaign ads for Rep. Elissa Slotkin in Michigan, Sen. Sherrod Brown in Ohio, Sen. Bob Casey in Pennsylvania, and Sen. Tammy Baldwin in Wisconsin focus on the Democratic candidates' alliance with Trump or his policies, implying that aligning with the former president may benefit their campaigns more than siding with Democratic presidential nominee Kamala Harris.

While Trump is behind Harris by 1.4 points according to the RealClearPolitics polling average, he leads the vice president in every battleground state.

Slotkin, who is running for Senate, released an ad in which she criticized electric vehicle mandates and promoted manufacturing EVs in the U.S.
