Sen. Bernie Sanders (I-VT) did not provide a direct answer when asked if Pennsylvania Democrats are hurting Vice President Kamala Harris’s electability in the state.

Sanders was asked about a new ad from Sen. Bob Casey (D-PA) that shows the Pennsylvania Democrat boasting about how he “bucked Biden to protect fracking” and sided with Trump over placing tariffs on China “to stop them from cheating.” The release of the ad comes as former President Donald Trump seeks the White House again and Casey is seeking reelection against Republican challenger Dave McCormick in the 2024 elections.
