Mitt Romney has won the Republican nominating contests in five states — Idaho, Ohio, Vermont, Virginia and Massachusetts, the state he once governed.
"We're going to get more [wins] by the time this night is over," said Romney early Tuesday evening." Tonight we're doing some counting. We're counting up delegates."
Romney apparently pulled off a narrow victory in Ohio over Rick Santorum, but the vote was close enough that a recount may be called.
Newt Gingrich added a win in his home state of Georgia to an early triumph in South Carolina.
Georgia allocates 31 delegates toward the Republican nomination, and The New York Times projects that they will be split between Gingrich and Romney.
The Times projects that, because the Virginia primary is largely uncontested, Romney will take all 49 of its delegates but that he will gain few in Vermont, which allocates most of its 17 delegates on a proportional basis.
His chief rival, Santorum, kept the pressure on with wins in Oklahoma, North Dakota and Tennessee.
Romney enjoyed convincing victories in Virginia and Vermont, CNN's results show.
Due to what can only be called campaign errors, Gingrich and Santorum didn't appear on the ballots in Virginia, allowing Romney to walk away with an astounding 43 delegates. Only Paul provided opposition, and earned 3 delegates for his efforts.
In Vermont, Romney captured 8 delegates thanks to 40 percent of the vote. Paul and Santorum were well back with 25 and 23 percent, respectively, and 3 delegates each.
"Tonight, we're doing some counting," Romney said, MSNBC reported. "We're counting the delegates for the convention and that looks good, and we're counting down the days to the convention, and that looks better."
As the evening came to a close, the Romney campaign chalked up Idaho.
Romney took 69 percent of the Idaho count over Paul (17%), Santorum (12%) and Gingrich (3%).
