I found this Texas Monthly article with the money quote "If Perry defeats Hutchison in the March 2 Republican primary and goes on to win a third full term in November, he will immediately join the crowd of potential presidential aspirants in 2012—if he hasn’t done so already." So if another source can be found (dated within past six months, of course) he'll be added. This seems likely to happen, now that you've put him on the editors' radar screen.
