While Gingrich earlier in the week indicated that he would consider running if he learns that supporters would pledge $30 million for his campaign, the former speaker said Sunday that he would be “compelled” to run if the resources are there.

“I think the odds are very high, if we ended up with that level of pledges, I don’t see as a citizen how you could turn that down,” Gingrich said on Fox News Sunday. “How could you turn to all of your fellow citizens - if they walk in and say, ‘You know, we think you’re the person who ought to debate Senator Clinton, and we think you’re the person who can actually explain where we ought to go,’ how could you turn to them and say, ‘Well, I’m too busy?’

Gingrich adviser Randy Evans will test the waters over the course of the next month to see if the resources are out there that Gingrich believes could propel him to the GOP nomination.

“I mean, there’s no point in getting into a fight with a guy who can drown you unless you at least have enough resources for a vote,” Gingrich said, noting that former Massachusetts Gov. Mitt Romney (R) could write his own campaign a $100 million check.

The former speaker said he believes that he has enough time to run a successful campaign.

“I think in the age of television, we are reaching more people today than Abraham Lincoln reached personally his entire career,” Gingrich said. “We have many friends across the country. If we have enough friends, I think we could mount a campaign in a matter of weeks.”
