Two openly gay Republicans backed by House Speaker John Boehner lost their House bids on Tuesday.

Voters in Massachusetts' Sixth Congressional District picked first-time candidate Seth Mouton, an Iraq war veteran, over Richard Tisei, who conceded defeat on Tuesday night around 9:40 PM.

Tisei's loss is his second in two years for the same seat. In 2012, Tisei lost by less than one percentage point. This year, he trailed Mouton by nearly 14 percentage points.

The 52-year-old married Tisei is a real estate agent who served in the Massachusetts Legislature for 26 years.

The race to represent the people of California's 52nd Congressional District was much tighter, with freshman Democratic Rep. Scott Peters narrowly edging out Republican Carl DeMaio (51.25% to 48.75%). The race was so tight that it wasn't called for Peters until Friday.

DeMaio, a former San Diego city councilman, was handicapped by last-minute accusations of sexual harassment by a former campaign staffer.

Todd Bosnich, who is gay, told CNN in October that DeMaio had sexually harassed him during his time with the campaign and that he was offered $50,000 by the campaign to sign a non-disclosure agreement.

DeMaio denied the allegations, calling them “absolutely untrue.”

A DeMaio spokesman said at the time: “The individual making the claims was fired from the campaign months ago for plagiarism. The individual only made these false allegations after the San Diego Police Department started investigating him as the suspect for the campaign office break-in.”

While open about his sexuality – in campaign ads, he declared himself a “proud gay American” and was shown holding hands with his boyfriend at San Diego's Gay Pride Parade – DeMaio has faced criticism in the past over placing a low priority on issues related to gay rights.
