Conservatives like GOP ad attacking Harris in swing states.

Conservatives on social media are praising a blistering ad launched by Pennsylvania Republican Senate candidate Dave McCormick linking his opponent, Sen. Bob Casey, to the policies of presumptive Democratic presidential nominee Kamala Harris.

“Kamala Harris is inspiring and very capable,” a clip of Casey says at the start of the ad released by McCormick on Tuesday.

The ad then goes into a variety of clips of Harris promoting progressive policies and labeling her the “most liberal nominee ever.”

In the ad, Kamala is quoted calling for the elimination of the filibuster, banning fracking, decriminalizing illegal immigration, abolishing ICE, defunding the police, mandating a gun buyback program, and other liberal policies.

The ad, which was viewed over 1.5 million times in 24 hours, was quickly praised by conservatives on social media.

“Most comprehensive anti-Harris ad I’ve seen so far,” journalist Mairead Elordi posted on X.

“Attention Republicans,” conservative commentator and author Matt Walsh posted on X. “This is how you attack Kamala Harris. Here’s the blueprint.”

“The most radical presidential candidate in American history – just listen to her,” GOP Sen. Bill Hagerty posted on X. “America would never be the same if even half of these policies were carried out.”

“One of the most brutal and effective ads I’ve seen in a while,” Trump delegate Christian Ziegler posted on X. “Just play this every moment from now until November on TV. Good work by whomever cut this one.”

“Congrats to Dave McCormick’s team… this is brilliant,” 1776 Project PAC Founder Ryan James Girdusky posted on X. “Now get it streaming online and on TV.”

Casey’s seat is widely regarded as one of the best chances Republicans have to take back control of the U.S. Senate in November. The Cook Political report ranks the race as “Lean D.”
