With the four major Republican presidential candidates battling it out in 10 states on Super Tuesday, Newt Gingrich is focusing on winning Georgia, the state he represented in Congress for two decades.

Gingrich crossed the Peach State in a three-day bus tour this week, and there are signs he is headed for a win there in Tuesday's primary. At stake are 76 delegates, which will be divided proportionally among the candidates.

The former congressional leader leads two polls of Georgia unveiled Friday.

With 10 states on the line on Super Tuesday, eyes are turning to Ohio, where Rick Santorum and Mitt Romney are locked in a tight struggle and focusing their efforts.

A third showed Santorum with a larger lead. There are 66 delegates at stake in Ohio which will be divided on a proportional basis.

While Mitt Romney handily defeated John McCain in Michigan in 2008, two polls taken on Sunday show that this years Republican presidential primary Tuesday should be much closer.

Despite being born there and his fathers tenure as governor of the state, Romney tumbled in the polls in the Great Lakes State after he lost to Rick Santorum in contests in Colorado, Minnesota and Missouri earlier in the month. Some polls even showed Santorum ahead of Romney by double digits.
