Republican Congressional candidate Bob Dutton has felt the sting of the state GOP endorsing his same-party opponent, incumbent Gary Miler.
California's so-called "jungle" primary created several interesting pairings for the November ballot. Democrats are facing off against Democrats in half-a-dozen Congressional races. On the GOP side, it's Republican vs. Republican in two House races.
Some of these contests are under the radar, but a few have erupted into nasty fights, splitting the parties themselves.
Republicans, who pride themselves on avoiding intra-party explosions, have waded into a big one in the Inland Empire.
The party endorsed incumbent Congressman Gary Miller over his challenger, State Senator Bob Dutton. And adding salt to the wound, it used some of the money raised by Dutton to run ads slamming him.
Dutton has been a party loyalist. He served on the GOP's board of directors and raised more than $100,000 for party causes and candidates. Oh, and he was the top Republican in the State Senate the past two years as well.
