Texas Attorney General Greg Abbott (R) will have to sign an affidavit in order to vote thanks to Texas’ new voter identification law.

The GOP-backed voter law requires voters to verify their identity with certain photo identification to a pre-approved voter list. If there are slight discrepancies between the names on the list and the identification presented, voters can sign an affidavit to move forward and vote.

And now Abbott will have to sign an affidavit, his spokesman told The San Antonio Express-News, because the name on Abbott’s driver’s license is Gregory Wayne Abbott while his name on the voter registration list is just Greg Abbott.

State Sen. Wendy Davis (D), Abbott’s likely Democratic opponent in the governor’s race, also had to sign an affidavit earlier this week.

Abbott his been an outspoken proponent of the voter ID provision that requires a photo ID to vote. He plans to vote early in the November election, according to Abbot spokesman Matt Hirsch.
