Sen. Dan Patrick isn’t putting much stock in Lt. Gov. David Dewhurst’s new endorsement. Land Commissioner Jerry Patterson announced yesterday that he would campaign for Dewhurst ahead of the May 27 runoff election. Patterson placed fourth in the Republican primary and has been one of Patrick’s more outspoken critics.

In a statement today, Patrick campaign manager Logan Spence said:

“Since his fourth place finish in the primary, Jerry Patterson has been helping Dewhurst, so this really come as no surprise to anyone.  Dewhurst and Patterson share the same Private Investigator and the same penchant for dishonesty and vicious personal attacks.  Republican Primary voters soundly rejected that in favor of Dan Patrick who offers conservative public policy solutions; and we expect the Republican Runoff voters to do the same.”

Patrick placed first in the GOP primary, ahead of Dewhurst by about 13 percent of the vote. It wasn’t enough, however, to win outright.

During the primary, Patterson hired a private investigator to look into Patrick’s previous business ventures. He discovered Patrick employed four undocumented workers at one of his Houston-area sports bars in the 1980s. Patrick has denied that he knew the workers were in the country illegally and maintained that he never offered to help the employees travel back and forth to Mexico.
