But, Gingrich is now looking to monetize those interactions, according to media reports. Instead of just posting a picture of Gingrich and supporters directly to the candidate's website, as they have in the past, campaign staffers are giving interested individuals a credit card form to fill out in order to access the pictures.

Gingrich also canceled a Wednesday trip to North Carolina, opting instead to save money and campaign in and around Washington, D.C. 

The former House Speaker has seen his monthly fundraising totals drop off since being dealt a tough loss in the Florida primary, raising just $2.6 million in February. Earlier this month, Gingrich spokesman R.C. Hammond said the campaign was running about break-even, but Gingrich's inability to win in Alabama, Mississippi or Louisiana likely further strained donor relations.

Still, Gingrich vowed Monday to stay in the presidential hunt until Mitt Romney had secured the 1,144 delegates needed for victory, telling Fox News there was "a very real chance" the GOP front-runner falls "over a hundred votes short."

Gingrich also dismissed the notion that a brokered convention could hurt the party.

“The later we get a nominee, the less time Obama has to smear the nominee,” Gingrich said. "They’re going to raise the billion dollars, but what if they don’t know who to attack? What if they don’t know exactly what they’re doing?”
