President Bush's bid to amend the Constitution to ban same sex-marriage headed toward defeat on Tuesday, with Democratic foe John Kerry accusing him of divisive election-year politics.
Proponents scrambled to win the support of half of the 100-member Senate, but both sides said the measure seemed certain to be blocked on a procedural vote on Wednesday.
If its mostly Republicans backers are unable to get 60 votes to end debate and move to a vote on passage, the proposal will likely be dead for the year. But proponents vowed to try again next year.
"You've got to put senators out there and get a vote total, and then people will say, 'Hey, we disagree,"' explained Sen. Sam Brownback, a Kansas Republican and a leading backer of the measure. "People will react."
Polls show most Americans oppose same-sex marriage, but split on whether a constitutional ban is needed. Surveys also find voters believe a host of other issues are more important -- such as health care, education and national security.
Republicans forced consideration of the proposed amendment two weeks before Kerry, a U.S. senator from Massachusetts, will receive his party's presidential nomination at the Democratic national convention in Boston.
Kerry and his running mate, Sen. John Edwards of North Carolina, oppose same sex-marriage, but argue amending the Constitution is not the answer.
Like many Democrats, they say it should be left up to the states to define marriage. They also accuse Republicans of pushing the measure merely to rally their social-conservative base.
Republicans contend gay marriage devalues traditional marriage, which they say is a pillar of civilization, and should be outlawed for the sake of children. ..
