I don’t get it either.

(Reuters) — Arizona’s Republican Governor Jan Brewer on Monday vetoed two controversial bills, one mandating proof of U.S. citizenship to run for president, the other allowing guns on college campuses, in a clear setback for conservatives who control the state legislature.

Brewer, who grabbed headlines a year ago when she signed a get-tough state law cracking down on illegal immigrants, vetoed the bills in an announcement late on Monday.

The so-called “birther bill,” would have made Arizona the first state in the nation to require presidential candidates prove U.S. citizenship by providing a long form birth certificate, and other forms of proof including baptismal or circumcision certificates, to be placed on the state ballot.

“I never imagined being presented with a bill that could require candidates for president of the greatest and most powerful nation on earth to submit their ‘early baptism or circumcision certificates’ . . . This is a bridge too far,” she said.

A former Arizona secretary of state, Brewer said she did not support designating one person as “gatekeeper to the ballot for a candidate,” as it “could lead to arbitrary or politically motivated decisions.”
