Updated 12:45 a.m. | It’s 8 p.m. on the East Coast, and Mitt Romney, Newt Gingrich and Rick Santorum have all picked up victories so far as the Super Tuesday showdown for Ohio remains uncalled.

Gingrich won his native state of Georgia by a wide margin — he represented the state for two decades in Congress, including his four years as Speaker. Romney easily picked up Massachusetts, where he served as governor from 2002 to 2006, as well as Vermont and Virginia. Oklahoma was quickly called for Santorum, the former Pennsylvania Senator.

But the real prize is Ohio, where Romney and Santorum are battling in a close race, according to early returns. Tennessee might also be shaping up as a close race between Romney and Santorum.

     Updated 9 p.m.

Santorum has been projected the winner of Tennessee, his second victory of the night, as Romney and Gingrich battle it out for second. In Ohio, Romney and Santorum continue to stalk each other in a close race, with Romney leading Santorum 39 percent to 37 percent with 12 percent of precincts reporting. Still to come this evening are decisions from Idaho and North Dakota.

     Updated 10:15 p.m.

Santorum has been projected the winner in North Dakota. Rep. Ron Paul (Texas) was in second, Romney was in third and Gingrich fourth. Still outstanding are Alaska, Idaho and, of course, Ohio. The Buckeye State is too close to call nearly three hours after the polls closed, with Santorum holding a 38 percent to 36 percent lead with 70 percent of precincts reporting.

      Updated 11:20 p.m.

After trailing Santorum in Ohio all night long, Romney pulled ahead of the former Pennsylvania Senator just after 11 p.m., as the Buckeye State’s heavily populated counties around Cleveland and Cincinnati began to report their votes. However, the race was still too close to call as of this posting. With 88 percent of the vote in, Romney was edging Santorum 38 percent to 37 percent. It remained unlikely the race would be officially called Tuesday evening.

Also Tuesday, Romney was projected to handily win Idaho, leaving only Ohio and Alaska outstanding. Super Tuesday’s tally for now: Gingrich won Georgia; Romney won Idaho, Massachusetts, Vermont and Virginia; and Santorum won North Dakota, Oklahoma and Tennessee. Paul did not post a win.

     Updated 12:45 a.m.

Romney has been declared the winner in Ohio, albeit by a narrow margin. But, as they say, a win is a win. Now the fight for the GOP nomination moves on to Alabama and Mississippi, two Southern states that hold their primaries next Tuesday. Romney is not expected to do as well in those states, although with Gingrich and Santorum still splitting the majority of the social conservative vote, anything is possible.

That’s a wrap for us tonight. Good night.
