“We cannot afford four more years of President Obama,” said Josh Romney, the third of Mitt Romney’s five sons. “We need someone to step in there and turn things around.”

But Josh had to stop repeatedly as people booed and yelled for Paul, who has continued campaigning in the Republican primary. All other challengers, including Rick Santorum and Newt Gingrich, have dropped out of the race, and Romney has a commanding lead over Paul in the estimated delegate count…

But as Josh wrapped up, with an admonition to choose the preferred slate of Mitt Romney delegates, the crowd exploded with competing boos and cheers, cutting him short.

Some attendees said they heard Paul supporters chanting outside that Mitt Romney is “the white Obama.”
