That would be Speaker Boehner... Speaker of the House of representatives...
The one constitutionally charged with the task of certifying election results as well as candidate eligibility.
Perhaps Arpaio was able to get one of them (SOS Ken Bennett or AG Tom Horne) to closely examine the evidence of the forgeries or alternatively new evidence of foreign birth.
Bennett had to honor the HI “authentication” of the existence of a birth record of some sort in HI as sufficient to allow Barry onto the AZ ballot, but that HI authentication of HI records doesn’t explain or absolve Barry from complicity in presenting to the voting public a clear forgery.
Note that having a forged BC doesn’t prove ineligibility, so additional evidence would have to have been found, IMO.
