Tonight at 6 pm our time, Logo and the Human Rights Campaign co-host a gay, gay, gay presidential debate featuring six of the top Democratic Contenders.

Hillary Clinton, Barack Obama, John Edwards, Bill Richardson, Dennis Kucinich, and Mike Gravel all plan to participate in the historic event.

From the Washington Post:

Human Rights Campaign president Joe Solmonese will serve as a panelist, along with singer Melissa Etheridge and Washington Post editorial writer Jonathan Capehart.

“I hope we can get genuinely heartfelt answers,” said Solmonese, who wants the leading candidates to explain why they remain wary of gay marriage.

Organizers say the forum marks the first time that major presidential candidates will appear on TV specifically to address gay issues…

All of them support a federal ban on anti-gay job discrimination, favor repeal of the “don’t ask, don’t tell” policy barring gays from serving openly in the military and support civil unions that would extend marriage-like rights to same-sex couples.

But thus far, only two longshots—Rep. Dennis Kucinich of Ohio and former Alaska Sen. Mike Gravel—have endorsed nationwide recognition of same-sex marriage, which a majority of Americans oppose.

I don’t have Logo, but I’ll be watching the live stream online. (That site’s already being a bit pokey, though—hopefully I won’t have too many technical difficulties tonight.)
