One of the clearest signs yet that the Republican Party is off the rails and over the cliff: Romney Camp Stands by Trump After Latest Birther Comments.

(CBS News) Mitt Romney’s campaign stood by its decision to use Donald Trump as a top surrogate even as the reality television host continues to insist President Obama was not born in the United States.

Romney is scheduled to appear at a Las Vegas fundraiser Tuesday with Trump, who made headlines last year with his “investigation” of Mr. Obama’s birth certificate. …

In a new interview, Trump pointed to a recent report that Mr. Obama’s literary agency listed him in a 1991 booklet as having been born in Kenya.

“He didn’t know he was running for president, so he told the truth,” Trump told The Daily Beast. “Now they’re saying it was a mistake. Just like his Kenyan grandmother said he was born in Kenya, and she pointed down the road to the hospital, and after people started screaming at her she said, ‘Oh, I mean Hawaii.’ Give me a break.”

A former assistant at the literary agency has said the printing was a clerical error.

Today Romney adviser Kevin Madden said the candidate disagrees with Trump, but would continue to campaign with him.

At this point, I’m not really surprised by this news. More like a sort of weary disgust. A GOP presidential candidate openly courting a crazed conspiracy theorist who claims the first black President of the United States was actually born in Kenya. Good grief.

And please note: Donald Trump is citing one of breitbart.com’s utterly moronic BOMBSHELL EXCLUSIVES as evidence Obama was born in Kenya — the BOMBSHELL EXCLUSIVE that contained a disclaimer saying it was DEFINITELY NOT evidence Obama was born in Kenya.
