While I personally support gay marriage, I suspect that the "civil union" compromise is about the best that mainstream America is willing to offer at the present time. Nor is that much of one, it's merely a matter of semantics.
I kinda like bozack's idea, eliminating the "M" word entirely form the legal lexicon. The requirements have been loosening up a lot over the years, anyway- at one time it was illegal to marry outside one's faith, not to mention race, divorce was unheard of, and women didn't need suffrage- their husbands voted for them. Today, the mere representation of marriage is, in fact, marriage- in Colorado, anyway. Sign in at the no-tell motel as mr. &.mrs., and you are, with everything that entails.
To label Kerry as a bigot in this matter is not exactly honest, given the examples of true bigotry from the other side. He's a realist, and a candidate who doesn't want to get sidetracked into a no-win irrational red herring issue.
The next thing I'd expect from the Bushies is an attempt to link gays, terrarists, taxes and gun-grabbers into a vast liberal conspiracy.... against God, True Believers, and their anointed worldly leader, GWB... I can see it now, Dubya in his flightsuit, spouting thinly veiled hate, old glory waving behind him, the chorus from "Onward Christian Soldiers" coming up in the background.... stirs my heart, brings tears to my eyes that we could have been blessed with such a wonderful leader, I'll tell ya...
