Evangelical pastor Ted Haggard is only alleged to have had a three-year sexual relationship with a male prostitute, but in politics, even a hint of something like that can be enough to sink a campaign.

The potential scandal may be enough to affect Tuesday's vote on the state constitutional ban on gay marriage or the domestic-partnerships initiative, some political watchers say. But who might benefit is anybody's guess.

Especially since gay marriage and benefits are usually bedrock issues and not prone to wavering opinions.

"Does this reinforce the liberal position of partnerships, or does it reinforce conservatives, who are saying we want less of these threats?" said Denver pollster Floyd Ciruli. "There are some people - but not very many - who are undecided, and this news could affect their vote."
