Stephen Colbert Asks: Could Marijuana Drive Obama Voters to the Polls? (Video)

Colbert on "the ultimate grassroots campaign"

Stephen Colbert has a theory about how President Obama could win a second term in November.

In 2004, Colbert noted, anti-gay marriage initiatives in several swing states helped draw out conservative voters who supported George W. Bush.

"'Cause nothing gets value voters to pull the lever like the though of two guys pulling each other's levers," Colbert said on Thursday's "Colbert Report."

This year, he said, swing states including Colorado, Ohio and Michigan may have pro-marijuana initiatives on the ballot. They could draw out liberals who will vote for Obama.

"This is the ultimate grassroots campaign," Colbert said. "These pro-pot initiatives, if they make it onto the ballot, I say Romney is doomed. 'Cause we all know pot smokers are highly motivated, organized and punctual. There is nothing they would love more than getting off the couch, putting on pants, and going to high school gyms packed with judgmental old people."

He added: "Romney's only hope is that on Nov. 6, Discovery runs a 'Planet Earth' marathon."
