NEW YORK -- On Election Day, it's officially going to be Obama for the Material Momma.

Madonna pledged her allegiance to the Democratic Party at the premiere of her directorial debut, "Filth and Wisdom," in New York on Monday night.

The pop icon, in the midst of her [article id="1593432"]Sticky & Sweet Tour[/article], continues to keep politics center stage, launching an impromptu campaign against the Republican vice-presidential nominee, Alaska Governor Sarah Palin, during shows in New York and New Jersey last week.

Madonna first banned the governor from the tour. In between sets, she screamed, "Sarah Palin can't come to my party! Sarah Palin can't come to my show!" As the week progressed, Madonna even threatened to "kick her ass."

But Madonna played down the trash talk on the red carpet of her movie premiere.

"It's a metaphor," she said. "She's in the Republican Party, I'm in the Democratic Party."

When asked if it's safe to assume she's voting for the Obama/Biden ticket, Madge told MTV News, "Hell, yeah!"

Politics get a regular slot in Madonna's current concert routine through dramatic video montages. During the song "Get Stupid," John McCain's face pops up on a screen right next to murderous dictators including Nazi leader Adolf Hitler and Zimbabwe's Robert Mugabe.

Meanwhile, the next act features happy pictures of Obama, alongside John Lennon, Mahatma Gandhi and Al Gore.

"Filth and Wisdom," which opens nationwide Friday, is a musical comedy starring Vicky McClure, Holly Weston and Eugene Hutz, lead singer of Gogol Bordello.
