Elizabeth Warren votes in Cambridge, Massachusetts

Massachusetts Sen. Elizabeth Warren, arrived at a polling center in Cambridge, Mass as she struggled for delegates and momentum on Super Tuesday.

Fourteen states and one U.S. territory are holding nominating contests with one-third of delegates at stake.

"This is a righteous fight, it is the right fight to be in," she said.

Warren has vowed to stay in the race until the party's national convention in July.
