Whitmer, Shapiro campaign for Harris in Bucks County, Pa.

Pennsylvania Gov. Josh Shapiro (D) and Michigan Gov. Gretchen Whitmer (D) hit the campaign trail for Vice President Harris in Bucks County, Pa., on Monday. 

The two battleground-state governors praised Harris’s record as vice president but did not hold back in their attacks against former President Trump. 

"I've got a message to Donald Trump: Stop s‑‑‑ talking America,” said Shapiro, a leading contender to be Harris’s running mate. “This is the greatest country on the face of the Earth. Let's start acting like it."

Shapiro went on to paint Trump as “weird,” an insult echoed by a number of other Harris surrogates and vice presidential contenders in recent days. 

“You ever see this guy? He kind of meanders over and goes over to the flag and hugs the flag. I love the flag, but it’s a weird thing he does,” Shapiro quipped. 

The campaign stop comes as the Harris campaign fans out its surrogates across the country. Bucks County is known as one of the most competitive counties in the country and could be decisive in swing-state Pennsylvania. 

The Harris campaign is targeting the must-win “blue wall,” which comprises the states of Pennsylvania, Michigan, and Wisconsin. 

Whitmer sought to link the three states on stage on Monday. 

“Pennsylvanians are a lot like Michiganders, and a lot like Wisconsinites for that matter,” Whitmer said. 

“We are the party, as Gov. Shapiro likes to say, of real freedom for Americans,” she continued. 

The latest polling from The Hill and Emerson College shows Harris tied with Trump at 47 percent support in Wisconsin, and trailing him by 2 points in Pennsylvania and by 1 point in Michigan.
