Sen. Ted Cruz (R-Texas) was met with enthusiastic cheers from an “adoring” audience during his address at a conservative summit on Saturday, the friendliest of any of the potential 2016 presidential hopefuls to speak at the Defending the Dream summit.

The event, hosted by Americans for Prosperity, drew a handful of other conservative stars and would-be presidential contenders: Sen. Marco Rubio (R-Fla.), Texas Gov. Rick Perry (R ) and Louisiana Gov. Bobby Jindal (R ) all spoke.

But according to The Washington Post, none received so warm a welcome as Cruz. He was met with chants of “Run, Ted, run!” after giving a speech focused largely on the imperative of defunding ObamaCare, a cause which he and a handful of other conservatives in the Senate have championed in recent weeks.

Cruz slammed fellow Republicans who have criticized the push as potentially politically harmful and pledged not to back down from a threat to shut down the government if the law is not defunded.
