Last week, Cantor went farther than most mainline Republicans have in dismissing the Trump quasi-campaign. He told CNN that Trump's embrace of birtherism is a sure sign Trump is fooling around.
"I don't think he is really serious when we see a campaign launch on the birther issue," Cantor said.
Other mainstream Republicans joined the chorus as polls showing Trump leading the Republican presidential field made headlines at the end of the week. On Friday, Karl Rove told Fox News Trump is a "joke candidate" because of his birther-centric media cavalcade.
"He's off there in the nutty right, and is now an inconsequential candidate," Rove said.
Today in Boca, Trump seemed to relish the criticism from members of his own party. In his speech to the tea party rally, he excoriated Rove. The tea partiers, no fans of Rove from back in the days of Christine O'Donnell, booed Rove's name when Trump mentioned it.
"It's amazing," Trump said. "He's so against me, because I am questioning. All I want to see is the guy's birth certificate."
"The Republicans have to be very careful of him," Trump continued. "Because obviously Karl Rove hasn't been doing very well the last couple of years...Whether you like it or not, George Bush gave us Obama, and I'm not having that."
