Former House Speaker Kevin McCarthy (R-Calif.) has some advice for Donald Trump : ditch his focus on the large crowds attending the rallies for his Democratic rival, Vice President Kamala Harris .

In a Monday interview on Fox News , McCarthy said Harris was the perfect person to run against because, he claimed, she is the biggest flip-flop on policy, but indicated the former president is squandering the opportunity.

The new Democratic Party ticket appears to have generated a groundswell of support, as witnessed by around 15,000 people turning up to a rally near Detroit last Wednesday.

Trump on Sunday claimed a photo from the event had been AI-generated a suggestion that was quickly and widely debunked and continued to rant about crowds at his own rallies.

Youve got to make this race not on personalities, McCarthy said, apparently reflecting wider GOP frustration with Trumps recent tactics. Stop questioning the size of her crowds and start questioning her position, when it comes to: What did she do as (California) attorney general on crime? Question what did she do when she was supposed to take care of the border as a tsar?
