DES MOINES —
In the congressional races, King won a sixth term, his toughest challenge yet, beating Iowa's former first lady Christie Vilsack, a Democrat.
Braley won a fourth term, beating Republican Ben Lange in Iowa's 1st Congressional District. It was the second time Braley has beat Lange, who narrowly lost his congressional bid in 2010.
Loebsack was elected to a fourth term representing southeastern Iowa's 2nd Congressional District, beating Republican Bettendorf lawyer John Archer.
Iowa voters also were tasked with deciding whether to retain an Iowa Supreme Court justice who supported gay marriage.
Sylvia Fanelli, 34, of West Des Moines, said Obama's support of gay marriage was a big reason she chose the Democrat. She also voted to retain Justice David Wiggins, who joined in the unanimous 2009 ruling that legalized same-sex marriage.
"I think that man is an awesome judge," Fanelli said. "I think he's doing the right thing and he did the right thing voting for marriage equality in this country."
In the Legislature, Republicans hoped to win a majority in the state Senate, which would let them move ahead with an ambitious agenda backed by GOP Gov. Terry Branstad.
