Susie Buell of San Francisco voted for Hillary Clinton in the California primary. Her vote is counted, the delegates for Clinton guaranteed seats when the Democratic National Convention opens in Denver in August.

But she couldn't stay home when she heard the Democrats would debate whether to seat delegates from Florida and Michigan.

"We want every vote in America counted," Buell said, standing outside DC's Marriott Wardman Park hotel with hundreds of fellow protestors.

Amy Rao of Palo Alto likened it to what happened in 2000, when Democrats claim that Florida did not count all the votes for Al Gore and threw the election to George Bush.

"We will not let that happen again," Rao said.

Her California group all wore T shirts declaring, "We spoke loud and clear. Our voices must be heard."

Among other signs:

"Voting rights = civil rights."

"Woman Arise. Stop the Bias!"

The Rules and Bylaws Committee of the Democratic National Committee starts its meeting at 930 am EDT.
