From today's USAToday:

Bush announced his support for the amendment last February, but recently has come under pressure from some of his conservative allies to give the issue a higher profile.

Paul Weyrich, national chairman of an amalgam of conservative organizations known as Coalitions for America, recently said that Bush needs to change the subject from Iraq to the gay marriage ban in order to be re-elected in November.

Bush responded last week by reiterating his opposition to gay marriage in remarks to the Southern Baptist Convention, saying that "government, by strengthening and protecting marriage, serves the interests of all."
