“I look forward to supporting her during the transition in any way I can” Fain wrote in Facebook post.

He posted to Facebook just hours after the latest King County ballot drop showed Das extending her lead to more than 500 votes. If Fain had stayed in the race, there would almost assuredly have been a recount.

Once a rising star in the state Legislature and state GOP party, Fain’s re-election was clouded by accusations by former Seattle city official Candace Faber that he’d raped her in 2007 after a drunken Georgetown graduation party in Washington, D.C.

After the accusations were made in Septemberlast month, Fain’s spokesperson denied the accusation.

"I was shocked to learn that I was being accused of the conduct she has described as my memory of the events do not coincide with her allegations," Fain said in a statement then through his spokesperson. "I am again asking that she be afforded the utmost respect during what I believe must be a difficult time for her as well."
