AARP Crowd Boos Paul Ryan

Which may be the best endorsement he's received to-date

Speaking to an audience of seniors in New Orleans, Paul Ryan was booed after he called for a repeal of President Barack Obama's health care reform law, and faced one of his frostiest crowds since joining the GOP ticket.

"I had a feeling there would be mixed reaction, so let's get into it," Ryan said at the AARP's annual conference.

As Ryan asserted one of the main underpinnings of his candidacy — doing away with the federal health care law — the crowd chanted "no" and booed the Wisconsin representative more than once.
