(NEWSER) – Another name to add to the GOP mix for 2012: Rick Perry. The Texas governor publicly denies he’s considering a run, but Real Clear Politics reports that he “sees a vacuum and is waiting to be summoned into the race,” possibly by late summer. Already, an aide is making discreet inquiries in Iowa. With Haley Barbour and Mike Huckabee out, and Newt Gingrich tripping over himself at the starting gate, Perry could indeed fill a conservative void, write Erin McPike and Scott Conroy. One potential snag: Sarah Palin.
