His birtherism, that is. It seems to be rampant among Arizona Republicans.
Nearly half of the Arizona Legislature wants to force President Barack Obama to show his birth certificate to state officials if he runs for re-election.
A state House committee on Tuesday approved the measure sponsored by 40 of the state's 90 legislators. It would require presidential candidates who want to appear on the ballot in Arizona to submit documents proving they meet the requirements to be president.
All 40 co-sponsors are Republicans, comprising 75 percent of the GOP caucus. Two of them have since resigned to run for Congress.
The idea was proposed by Skull Valley Republican Rep. Judy Burges. She says if people have to prove their citizenship to apply for a job or get a passport, they should have to prove it to run for president.
With those kind of numbers his position on Obama's birth may help him vs McCain.
