The votes of hundreds of thousands of unaffiliated Rhode Island voters are up for grabs in the state's presidential primary.
Of five states holding primaries Tuesday, it's the only one where independent voters can select either the Democratic or Republican ballot. Half of Rhode Island's registered voters don't belong to either party.
Twenty-four of the state's 33 Democratic delegates, and 16 of the state's 19 Republican delegates, will be chosen.
Most polls opened at 7 a.m. and are scheduled to close at 8 p.m.
The state will have one-third fewer polls open than it does during a general election.
Pawtucket Registrar Ken McGill says he expects his city's turnout to be nearly as high as the 35 percent who participated in the 2008 primary.
Most top candidates have campaigned in the state.
