Voters are heading to polls across Georgia with much on the line for former House Speaker Newt Gingrich, who is looking to regain momentum in the race for the Republican presidential nomination.

Gingrich represented Georgia for 20 years and has been leading in state polls over Mitt Romney, Rick Santorum and Ron Paul. Georgia has the most delegates up for grabs on Super Tuesday. The polls will be open from 7 a.m. until 7 p.m.

Voters in 53 counties and 29 cities are also considering local sales tax measures, Sunday alcohol sales, and special elections for local offices.

Gingrich has focused extensively on Georgia, spending much of last week here rather than campaigning in the other Super Tuesday states. Rivals Romney and Santorum have also dedicated time and resources in the state.

Other states holding Super Tuesday contests are Alaska, Idaho, Ohio, Oklahoma, Massachusetts, North Dakota, Tennessee, Vermont and Virginia.
