Politico writes that organizers at the Conservative Political Action Conference (CPAC) have been instructed to urge attendees not to boo Senator John McCain when he makes his appearance there today.

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.”

“Are you kidding me?” the shocked CPAC-goer asked.

“Well, we want to seem above Democrats and we don’t want the booing to be the story,” the CPAC person declared. When asked for a response, CPAC’s Ian Walters told us: “We would hope that our folks would be polite and give him a fair opportunity to be heard.”

CPAC is an annual event that often generates lots of news. Speakers will include the remaining Republican presidential candidates, President Bush, Vice President Cheney and other conservative luminaries.
