Rep. Jason Chaffetz (R-Utah), a key surrogate for Romney, called the Ron Paul protest at the RNC "as expected."

"We march on," said Chaffetz, as he strolled on the floor near the Utah delegation. "Hopefully they've got it out of their system."

Paul's Maine delegates, who lost a bid to be seated, have walked off the floor. But some disgruntled Paul supporters continued to protest in the hallways of the Tampa Bay Times forum.
