"I know that [he was a POW]," Coulter declared, "because he mentions it more often than Kerry mentions he was in Vietnam. There were hundreds of POWs and we are not going to make all of them president. Can't we find a POW who doesn't want to shut down Guantanamo."

No topic was out of bounds, including the five years McCain spent as a prisoner of war in Vietnam.

Speaking before the Young America's Foundation, who invited her over CPAC's objections, the conservative author spent most of her time viciously attacking her party's new presumptive presidential nominee, Sen. John McCain.

As for former New York City mayor Rudy Giuliani: He "enthusiastically supported torturing terrorists," she said to great applause. "McCain hysterically opposes dripping water down the terrorist's noses."

And what if the unthinkable happens, and President McCain is inaugurated? I've led an impeachment movement before, Coulter said, and "I can lead another one."
