The nod for Dewhurst comes three weeks before the May 27 Republican runoff, in which Dewhurst faces state Sen. Dan Patrick of Houston. Patrick was the top vote-getter on primary day, beating Dewhurst by about 13 points.
“It is a very clear choice," Patterson, who currently serves as the state's land commissioner, told KERA News. "We have a person who has consistently proven to be unable to tell the truth versus one who has had some hiccups along the way but is a substantially better choice for lieutenant governor than somebody who has a history of not being able to tell the truth.”
The fourth candidate in the Republican primary, Agriculture Commissioner Todd Staples — who along with Patterson earned a combined 30 percent of the vote in March — has said he will not endorse in the runoff.

Patterson has been a forceful critic of Patrick, saying he would take the state backward as lieutenant governor, but had yet to officially back Dewhurst.
