Land Commissioner Jerry Patterson is taking his recent endorsement of Lt. Gov. David Dewhurst a step further, by appearing in a new campaign ad.

Entitled “Dan is Not the Man,” the ad features Patterson sitting at a table, cleaning his guns and telling the stories behind them. It’s not until halfway through the ad that Patterson introduces himself and talks about his former opponent in the Republican primary race for lieutenant governor, Sen. Dan Patrick.

“It’s pretty clear to me that Dan Patrick is not the right choice for Texas, and that David Dewhurst is,” Patterson says.

Patterson initially declined to endorse anyone after coming in fourth in the primary race, but got behind Dewhurst last week. Agriculture Commissioner Todd Staples, who was also a candidate for lieutenant governor, has so far decided not to back either candidate.
