The primary in Arizona is scheduled for February 28, 2012.
Note that we are in a leap year.
Since the AZ primary is 28 Feb maybe hes playing it safe so they can saqy Obama committed a crime by having his name illegally on the ballot on 28 Feb
if he brings his evidence out before Obama can ask for his name to be taken off and thus not have committed a crime etc...
weakening the sheriffs announcement in AZ...
or something...
