Ron Paul Supporters Boo Romney Son Off Stage at Ariz. GOP Convention

Supporters of Texas Rep. Ron Paul booed one of Mitt Romney's adult sons off the stage Saturday at the Arizona Republican Party convention as he tried to consolidate support for his father.

Josh Romney's speech to state GOP members was cut short by jeers from Paul backers at Grand Canyon University in Phoenix, the Arizona Republic reported.

The state's convention was to elect delegates for the national convention in August, where the former Massachusetts governor is expected to wrap up the nomination to take on President Barack Obama.

"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 Paul supporters have begun flooding state conventions, recently winning control of delegate majorities in Nevada and Maine.

Josh Romney tried to pacify the crowd by taking a moment to recognize his father's former rivals. It appeared to have little effect: Telling delegates to vote for his dad as he finished up, the crowd "exploded with competing boos and cheers, cutting him short."

According to the Republic, some attendees said they heard Paul supporters chanting outside that Mitt Romney was "the white Obama."
