Rick Perry Booed By Ted Cruz Supporters At Texas GOP Convention

Rick Perry was met with opposition by fans of Ted Cruz while speaking at the Texas Republican convention.

During his speech, Perry reaffirmed his support of Texas' Lieutenant Governor, who was forced into a runoff election for the U.S. senate by Cruz, the Lone Star state's former Solicitor General. Fans of Cruz, who has a strong Tea Party following, repeatedly shouted "Cruz" and booed during Perry's speech.

When asked about the crowd reaction, Perry seemed unaware of the protest.

"I thought they were saying 'Dewwwww,'" he said, according to the Texas Tribune.

It's not the first time Perry has seen tension over his support for Dewhurst. He recently slammed several other big-name Republicans -- including former Vice Presidential candidate Sarah Palin, former Republican presidential hopeful Rick Santorum and Senator Jim DeMint -- for getting involved in the race.

"I appreciate everybody paying attention to Texas -- as well they should," Perry said. "They could learn some things on how to run South Carolina and Pennsylvania and Alaska."

Dewhurst and Cruz will face off on July 31 to advance to the November general election. A runoff also will decide the Democratic primary.
