Paxton is undoubtedly the most popular statewide elected official in Texas. Regardless of any personal failings or potential (minor) corruption he has aggressively pursued cases for the benefit of the people of Texas (and by extension on many of those, the US as a whole). I just hope that his political ambitions don't end up with him in a position where he becomes less effective (which almost any "promotion" would do.) He should stay AG forever unless he can get appointed to the Supreme Court or maybe a US Circuit.
