With the ballroom packed with Ron Paul supporters, who are awaiting the libertarian congressman to speak, Virginia Gov. Bob McDonnell made a surprise appearance on stage -- entering to a roaring, standing ovation. Virginia Attorney Generla Ken Cuccinelli spoke here earlier in the day.

"Thank you for what you did for me. Thank you for what you're going to do for conservative candidates all across the United States of America," said McDonnell, who boasted his big win in a state President Obama won in 2008.
