Concord, New Hampshire (CNN) - Former House Speaker Newt Gingrich has raised more money in October than during the previous three months combined, he told reporters Tuesday as he laid out his vision for his campaign's turnaround.
During the previous fundraising quarter that spanned July, August and September, Gingrich raised $800,000.
The presidential hopeful was in New Hampshire to file his paperwork for candidacy in the state's presidential primary. He took questions from reporters after filing, then moved on to hold a second press conference across the street after signing an anti-tax pledge.
He said he was hopeful about his prospects as the race moves forward.
"If we continue to improve at this pace, I think we'll be able to run a full-blown campaign to be totally competitive in terms of advertising and other things, by the time we get to early January," Gingrich said.
The politician and professor attributed his financial bounce to his performances in a series of GOP debates this fall. Debate audiences have enthusiastically applauded Gingrich for chiding both the media and his opponents, accusing them of encouraging discord within the Republican Party. Instead he has urged the other GOP hopefuls to focus their criticism on President Obama.
"There was an unedited opportunity to listen to me and to decide that I had, that I actually represent a campaign of real substance," he said of his role in GOP debates. "Given the press coverage of June, July and August, that was sort of a great surprise to people."
Gingrich had a difficult summer after most of his staff quit en masse, questioning whether the former speaker was fully committed to the White House run.
He came in third nationally among Republican voters in a new CBS/New York Times poll, with 10% support.
