Former Republican presidential candidate Newt Gingrich predicts that GOP hopeful Mitt Romney will receive "more than 300 electoral votes" to defeat President Barack Obama on Nov. 6.

Speaking to Fox News host Greta Van Susteren on Thursday, the former House Speaker offered to "end the anxiety" for Fox News viewers.

"I believe the minimum result will be 53-47 Romney, over 300 electoral votes, and the Republicans will pick up the Senate," Gingrich said. "I base that on just years and years of experience."

"Take a look at the momentum. [Democratic strategist] James Carville taught me many years ago that if you're the incumbent, you get the last number in the poll [before the election]. You don't gain anybody."

Gingrich noted that traditionally blue states like Wisconsin and Pennsylvania were "starting to be in play."

"If you watch the president this morning, he's really rattled. He lost to [Illinois Democratic Rep.] Bobby Rush really badly in a primary many years ago, and I think he's getting that feeling that this could be like Bobby Rush and he could just go down," the former presidential candidate opined.

Contrary to Gingrich's rosy outlook, New York Times polling guru Nate Silver wrote on Thursday that "Romney's momentum seems to have stopped."

Silver explained: "Take Wednesday’s national tracking polls, for instance. (There are now eight of them published each day.) Mr. Romney gained ground in just one of the polls, an online poll conducted for Reuters by the polling organization Ipsos. He lost ground in five others, with President Obama improving his standing instead in those surveys. On average, Mr. Obama gained about one point between the eight polls."

"This is the closest that we’ve come in a week or so to one candidate clearly having 'won' the day in the tracking polls — and it was Mr. Obama."

As of 11 p.m. ET on Thursday, Silver's data indicated that Obama had a 73.1 percent chance of winning re-election, and would receive about 294.1 electoral votes to Romney's 243.9 electoral votes.
