State Sen. Chris Marr pointed to his election in 2006 to a seat that had been dominated by Republicans that change already is happening in Spokane.

He said he endorsed Obama more than a year ago because "he emodied the politics of possiblity, not the politics of negativity," Marr said.

Marr led a chant of "Yes we can!"

"This is a dead heat right now that we face," Marr said. "That means that each of us here will, not could, make a difference."

He is about to introduce state Sen. Lisa Brown, who will speak just before Michelle Obama.
