Vice presidential hopeful Senator Joe Biden appeared Monday on The Ellen DeGeneres Show, where he told chat show host Ellen DeGeneres that California's proposed gay marriage ban is “regressive” and that he would vote against it.

Biden congratulated Ellen on her recent marriage to actress Portia de Rossi and then spoke about Prop. 8.

“If I lived in California, I'd totally vote against Prop. 8,” the Delaware Senator said. “And, by the way, Barack and I opposed a similar attempt nationally. There was an attempt to talk about a constitutional amendment which I think is regressive, I think it's unfair. So, I vote no.”

“No on Prop. 8!” DeGeneres responded. “Fantastic! That's what I wanted to hear.”

In the last several weeks, DeGeneres has increased her vocal opposition to the gay marriage ban. Last week she announced she would spend $100,000 of her own money to buy TV airtime to promote her own commercial against the gay marriage ban.

Openly gay DeGeneres married her longtime girlfriend, actress Portia de Rossi (Nip/Tuck), in September. Her marriage is one of thousands in California that might be voided should the gay marriage ban pass.

Both Senator Biden and Senator Barack Obama have said they do not support gay marriage, opting instead for civil unions for gay couples, but both have expressed their opposition to constitutional gay marriage bans.
