Some local campaigners and political experts say today, known as "Super Tuesday," could make or break Democratic presidential candidate John Edwards' chance to win his party's nomination for president.
Ten states across the country hold Democratic caucuses or primaries today.
At the forefront of the states holding elections are New York and California, which offer more delegates than any other states - California having 370 pledged delegates and New York boasting 236.
Until today, Michigan was the state with the biggest delegate prize at 128.
Residents of Connecticut, Georgia, Maryland, Massachusetts, Minnesota, Ohio, Rhode Island and Vermont also are heading to the polls today.
