Newt Gingrich has won the Georgia primary, while Mitt Romney has won Virginia, Vermont and Massachusetts, CNN projected Tuesday night, using exit polls. Voting ended at 7 p.m. in the three states.
In Ohio, where polls closed at 7:30 p.m., early results of an exit poll of voters show Rick Santorum winning strong support from the most conservative voters, especially those focused on social issues like abortion.
Santorum had 39 percent of the Ohio vote, Romney had 37 percent, Gingrich had 15 percent and Ron Paul had 7 percent.
In Massachusetts, where polls closed at 8 p.m., Romney held a commanding lead, 70 percent, with Santorum far behind at 12 percent. Paul had 9 percent, Gingrich had 4 percent.
In Oklahoma, Santorum was the winner, Fox News projected shortly after polls closed, according to Reuters. It was the first victory of the night for Santorum.
In Tennessee, the vote was too close to project a winner. Exit polls showed Santorum ahead with 35 percent. Romney was in second place, the exit polls showed.
In Georgia, Gingrich had 47 percent of the vote, ahead of Rick Santorum's 25 percent. Mitt Romney had 22 percent, and Ron Paul trailed with 5 percent.
CNN projected Romney as the winner in Virginia, with 58 percent of the vote; Ron Paul got 42 percent, while Gingrich and Santorum were not on the ballot.
In Vermont, Romney was projected as winner with 39 percent of the vote, while Santorum was in second place with 24 percent, CNN said. Paul had 26 percent, and Gingrich had 8 percent.
Earlier Tuesday, results from exit polls in seven states holding Super Tuesday Republican presidential primaries show that the economy is the top issue across every state.
In addition, voters in all seven states are most seeking a candidate with the ability to defeat President Barack Obama in the November election.
The seven states voting in primaries Tuesday represent a wide range of Republicans, from the most moderate in Vermont and Massachusetts to the most conservative and religious in Oklahoma and Tennessee.
The focus Tuesday was on Ohio, a pivotal state for GOP hopes in November. There, nearly 8 in 10 express unhappiness with the government, including nearly 4 in 10 saying they are angry.
Practically every Ohio GOP voter expresses worry about the country's economy.
