"Alabamans want to feel like they are wanted and are being asked for their vote," Bill Armistead told CNN. "I think the more attention Alabama's paid, the more likely to give more votes, and so I would have to say that Speaker Gingrich is probably in the lead right now just from that alone."

Armistead said Gingrich has been campaigning "almost nonstop" in the state since last Tuesday. He added that Rick Santorum has also been in the state consistently, and Mitt Romney has "been in, but not quite as much" as his rivals.

"You would think he was running for governor here in Alabama because of his campaigning, going into restaurants, going to church on Sundays," he added about Gingrich.

Surveys of likely voters in the two states taken by Public Policy Polling (PPP) and released Monday showed a three-way statistical tie in Alabama and a tight race in Mississippi as well. Gingrich has a slight lead in the two states in recent polling, but within the margin of error.

Gingrich has banked his campaign strategy on winning the most delegates in Southern states, and seen success in the two states where he has won the vote so far: South Carolina and his home state of Georgia.

"In all reality if he doesn't win [both] Mississippi and Alabama it'll really be a big bump in the road" for Gingrich, said Armistead. "If he loses them both I really believe he's out of the ballgame."

Gingrich has maintained that he will go all the way to the GOP convention, and his daughter Jackie Cushman told CNN later on Tuesday morning that the Gingrich campaign sees the vote in Louisiana on March 24 as "halftime" in the primary race. She said that would be the reassessment point.
