The two Republican lieutenant governor candidates, David Dewhurst and Dan Patrick, faced off Friday night in a runoff debate. The debate took place at the studios of Houston Public Media. The runoff is May 27. The latest polls show Dewhurst, the current lieutenant governor, far behind Patrick, a state senator. Here’s a look at the race from KUHF, Houston’s public radio station: It's unusual for the incumbent to be unseated, but Lt. Gov. David Dewhurst is as many as 20 points behind state Sen. Dan Patrick in the polls.
