Sarah, Sarah, Sarah.

Former Alaska Gov.-turned-best-selling author Sarah Palin has jumped into the birther cesspool. She was asked today by a talk-radio jock whether the issue of President Obama’s citizenship is a legitimate issue.

Her answer was evasive and clumsy at the same time. The voters, she said, have made it an issue, so therefore it is “fair game.” She didn’t say precisely that she believes the nut cases who keep fanning the flames that question President Obama’s citizenship. She has hitched herself to the others’ bandwagon. In other words, if they believe that nonsense, then it’s OK with her.

It doesn’t matter to these goofballs that the state of Hawaii, where the president was born, has produced a birth certificate. Nor does it matter that two Honolulu newspapers published announcements of his birth — in Hawaii — back in 1961; the doubters thus have implied that the newspapers’ editors concocted a plot that makes the JFK conspiracy cultists look like rank amateurs.

These nut jobs have glommed onto the lies promoted by Obama-haters who just cannot stand the thought of this guy being elected president.

Now they can count a former governor — and current political superstar — as one of their own.
