So the only Conservative republican candidate has dropped out of the race:

MSNBC notes that talk host Laura Ingraham, who introduced Romney, blasted McCain in her speech: “She said of the three remaining Republican candidates, she’s glad to introduce ‘the conservative.’ She said it’s about ‘what you’ve done for us lately’ (read: not in the 80s when you claim to have been a foot soldier for Ronald Reagan). She then added, Let’s all ‘calm down’ for Mitt Romney — mockingly parroting McCain’s language yesterday.”

As Politico reports, McCain is hated so much that CPAC, which McCain has snubbed in years past, had to tell all it’s attendees not to Boo McCain:

John McCain may have it easier than he expected today when he commandeers the podium at CPAC this afternoon. Conservatives from all over will predictably fill the room to the brim to listen to what the now GOP front-runner has to say, despite a hate/love relationship with the guy.

CPAC it seems, is directing its loyal goers to not boo McCain. They must be more excited that McCain has finally signed on to appear after years of snubs than they want to let on.

During registration last night at the Omni Shoreham a registrant was asking to upgrade his CPAC package and then proceeded to ask what time GOP front-runner John McCain was going to speak today. “Oh good,” he said to the response — answer: 3 p.m. today– “I hope they boo him out of the room.”

“No, no no no no” came the reply from the person registering him. “We’ve been instructed to tell participants not to boo McCain.”

Here is a first-hand account of McCain’s arrival at CPAC:
