Congressional Democrats who don't agree with President Obama's endorsement of same-sex marriage now find themselves in an awkward spot.
Sens. Claire McCaskill of Missouri, Joe Manchin of West Virginia and Jon Tester of Montana are among Democrats facing questions about their stand on the issue and whether they are swayed by the president's support, which he announced Wednesday. McCaskill, Manchin and Tester are seeking re-election this year in Republican-leaning states. None back gay marriage.
"If they're smart, they won't change what they've been saying," said John Pitney, a political scientist at Claremont McKenna College in Claremont, Calif.
Republicans have called attention to Obama's announcement, which they say could pull votes away from Democratic candidates in Republican-leaning states.
"The president was looking at his own political prospects," Sen. John Thune of South Dakota, a member of the chamber's Republican leadership, said in an interview. "But if you're somebody from a Midwestern state, a fairly conservative state, it's probably not going to be helpful."
While Obama's endorsement was praised by gay rights advocacy groups and some Democrats in Congress, lawmakers from the party's more moderate wing have mostly stayed silent or reiterated their opposition to gay marriage.
Manchin, a former West Virginia governor running for Senate re-election in a state Obama lost by 13 percentage points in 2008, remains opposed to same-sex marriage, a spokeswoman said.
"His position hasn't changed; he believes marriage is between one man and one woman," Marni Goldberg said in an email.
Tester "supports civil unions for committed same-sex couples, but in Montana, marriage is between one man and one woman," spokeswoman Andrea Helling said Thursday.
Republican presidential candidate John McCain carried Montana by three percentage points in 2008.
McCaskill spokesman John LaBombard told the Springfield, Mo., News-Leader after Obama's announcement that while his boss opposes discrimination against homosexuals, she thinks states should "take the lead in determining marriage equality."
Missouri, which McCain won by a 3,600-vote margin in 2008, and Montana have state constitutional provisions defining marriage as being between a man and a woman.
A potential Republican opponent for McCaskill, Rep. Todd Akin, said Thursday in a statement that Obama's support for same-sex marriages showed the president's "unquenchable desire to tear down the traditional family unit brick by brick" and reiterated his opposition to gay marriage.
