Probably not, at least according to some GOP flacks speaking to the New York Times.
Republicans said that dwelling on the issue could become a distraction in the effort to win back the House or Senate from Democrats this fall. At a meeting of the Republican National Committee in Kansas City, Mo., several party leaders and strategists said it would be a mistake for the midterm election campaign to suddenly become focused on gay marriage, immigration or other hot-button issues. The only path to winning control of Congress, they said, rested on making an economic argument. “This election needs to revolve around five issues: taxes, spending, the economy, jobs and debt,” said Ron Nehring, chairman of the California Republican Party. “That doesn’t mean that other issues aren’t important — they are important — but the first issue on the minds of people is the economy.”
Likewise, Murray Clark, chairman of the Indiana Republican Party, said Republicans were acting at their own peril if they suddenly starting focusing on the ruling. A protracted discussion about social issues, he said, could play into Democratic hands. “Can we declare a truce on some of the other issues unrelated to the economy?” Mr. Clark said in an interview in Kansas City, Mo.
Also quoted in the above-linked article is NOM’s Brian Brown, who vows to make Prop 8 an election issue whether the GOP likes it or not. “I definitely think it’s going to have an effect on the 2010 elections. You’re going to see ads, you’re going to see folks standing up on this issue, and the people that support Walker’s decision are going to pay a price.”
