Vulnerable Senate Democrat Promotes Trump Ties in New Ad

Senator Bob Casey, Democrat of Pennsylvania, distances himself from the Biden administration and highlights his support of certain Trump administration policies in a new TV campaign ad that aired in parts of the state on Friday, signaling a last-minute appeal to the former president’s supporters in a crucial battleground state.

In the ad, two voters — a married couple made up of a Republican and a Democrat in Old Forge, Pa. — praise Mr. Casey as an independent lawmaker, saying that he “bucked Biden to protect fracking and he sided with Trump to end NAFTA and put tariffs on China.”

The spot aired nearly 100 times in Pennsylvania on Friday, frequently in heavily Republican areas such as Johnstown and Altoona, according to data provided by the tracking firm AdImpact.

The Trump campaign quickly seized on Mr. Casey’s references to Mr. Trump in the commercial, attacking the senator on social media for “desperately trying to embrace President Trump” and saying he was “a shill for Kamala’s deranged, radical left agenda.”

An official with Vice President Kamala Harris’s campaign in Pennsylvania said that Ms. Harris supports fracking, and that the ad was not an indication that Mr. Casey was separating himself from the vice president. When asked if Mr. Casey’s campaign had informed the Harris campaign about the ad before it aired, the official said that he would not discuss internal communications between the two campaigns.

Maddy McDaniel, a spokeswoman for Mr. Casey, said that the senator “always does what’s right for Pennsylvania, regardless of party,” and that “he stands with Pennsylvanians and doesn’t care what any politician has to say about it.”
