Georgia is Mr. Gingrich’s home state, and the former House speaker has doubled down there, hoping for a strong showing.
Right now, polls show Gingrich getting almost 45 percent of the vote, compared with about 25 percent for Mr. Romney and just under 20 percent for Rick Santorum.
Still, those results could still be good news for Romney. Not only would he emerge from Georgia with a number of delegates (like most of the Super Tuesday states, its delegates are awarded proportionally), but a solid win would give Gingrich the rationale he needs to stay in the race. Santorum’s best odds against Romney involve him consolidating the conservative, anti-Romney vote in a head-to-head matchup; with Gingrich still in the race, it’s hard to imagine him getting the support he needs.
