U.S. Rep. Steve Stockman (R-Texas) has endorsed the U.S. Senate campaign of State Senator Lee Bright – who along with three other challengers is vying to knock off incumbent fiscal liberal Lindsey Graham.

“He’s a proven conservative who understands the proper limited role of government,” Stockman said of Bright. “Whether it’s the Second Amendment, the right to life or fighting against Obamacare, Lee has built a record that would immediately make him one of the top conservative leaders in the U.S. Senate.”

Stockman, a freshman, is running against a fiscally liberal Republican for the U.S. Senate in Texas, challenging establishment Sen. John Cornyn. He achieved national notoriety by walking out of U.S. President Barack Obama’s State of the Union address earlier this week.

“I left early after hearing how the President is further abusing his Constitutional powers,” Stockman said. “I could not bear to watch as he continued to cross the clearly-defined boundaries of the Constitutional separation of powers.”

Bright – who earlier in the day admitted his fundraising was “struggling” – welcomed the good news.

“We are thrilled to have Congressman Stockman’s endorsement,” Bright said. “He’s tough, he’s principled, and he is in Washington to rein in Washington. Lindsey Graham is in Washington to unleash Washington, and Steve Stockman knows it, and that’s why he took the unusual step of endorsing a Republican challenger.  He knows I’ll join him and Ted Cruz, Mike Lee, Rand Paul and others to roll back this cancerous behemoth of a government.”

In addition to anemic fundraising, Bright’s campaign has been rocked by disastrous personal financial revelations – causing many to question whether he can be an effective messenger on bread-and-butter fiscal issues.

In other words it’s going to take a lot more than an endorsement from an out-of-state congressman to get his campaign back on track.
