Republican presidential candidate Newt Gingrich believes more prosperous days are ahead for his campaign, in terms of both poll numbers and dollar signs.

On his drive to Pella, Iowa, this morning for the National Association of Manufacturers Presidential Forum, Gingrich called into a local radio show, WOC’s “Morning Report,” with Dan Kennedy,  to talk about his increasing funds.

“Yesterday, we had the best day we’ve had in the entire campaign in fundraising online,” Gingrich said. “I just sense that every day that goes by now people are coming to us from other candidates, and say now that they’ve compared, they really want to be with me and very encouraged by that.”

The campaign is more than $1 million in debt but seems to show no sign of slowing down. He told Kennedy the campaign is opening up a number of offices in Iowa in the next week.

“We’re very encouraged now because we are clearly on the move,” Gingrich said. “Every indicator shows this in the polling.”

Gingrich appeared on the “ O’Reilly Factor” Monday night and told guest host Monica Crowley the campaign is working Iowa aggressively and has seen a  surge in his campaign fundraising.

“We’ve had the best month we’ve had in this campaign. We’ve raised more money in October than we did in any July, August, September and about half of June combined,” Gingrich said.

Gingrich also said he’s using social media to drive people to his website.

“I’m not going to raise the kind of money Mitt Romney can raise. I mean, he raised, I think, $5 million on Wall Street alone,” he said. “So the question is, can we find enough volunteers, and can we use social media, Facebook, the Internet, Twitter in order to compete with him? I think we can and we’re going to be very, very competitive in Iowa.”

The Gingrich campaign ranks among the top of the pack in social media, according to the Associated Press, which did an analysis of all of the presidential campaign tweeters. The AP monitored each presidential candidate’s use of Twitter since the day he or she joined the race and found the Gingrich campaign, which trails many other rivals in fundraising, to be one of the most active on Twitter. The former House speaker had Tweeted more than 470 times as of last Monday.

The Gingrich campaign could not be reached for details about the amount of funds in the campaign’s pocket.
