As Brian has written about quite a bit, there is some strife in the ranks of birthers over the potential presidential candidacy of Texas senator and Tea Party hero Ted Cruz.

Birthers believe (falsely) that President Obama was born overseas to one parent who was an American citizen and one who was not, and so, they claim, is not a “natural born citizen” eligible for the presidency. But many prominent birthers have made clear that they would be absolutely fine with the presidential candidacy of Cruz, who was actually born overseas to one parent who was an American citizen and one who was not.

Most mainstream legal observers hold that Cruz is still eligible to be president — just as Obama would have been even if he had concocted an elaborate scheme to lie about his place of birth — but the case highlights the hypocricy of the anti-Obama birther movement.

One prominent birther has at least decided to stay consistent. Richard Mack, a former Arizona sheriff who now heads the Constitutional Sheriffs and Peace Officers Association — a guild of officers who believe the county sheriff has the authority to defy and arrest federal officials — said in a recent Blog Talk Radio interview that he believes Cruz is ineligible for the presidency.

In response to a caller who argued that the Constitution bars the Canadian-born Cruz from being president, Mack said, “That is correct, I try to say that to a lot of people. Ted Cruz cannot run for president of the United States.”

“I like Ted, I’ve met him several times and he’s kind of a friend of mine, but he can’t run for president,” he continued.

Earlier this year, Cruz praised the efforts of Mack and his fellow anti-government protesters in their armed standoff against the federal government at Cliven Bundy’s ranch in Colorado.

Earlier in the program, Mack discussed the president’s birth certificate, saying that it was “real easy to determine that that was a fake and a fraud,” and alleged that the people “who helped fabricate all of these things and people who know about” aren’t coming forward because they’re “all fearing for their lives.”

“I know the person who has done this, they’re all fearing for their lives, obviously, but it’s time to come forward,” he pleaded. “The more light you shed on this, the less likely you are to be killed or hurt or put away.”
