Gingrich says his Iowa campaign needs no adjustment despite plummeting poll numbers

AMES, Iowa--Newt Gingrich probably didn't feel much like a candidate on the decline when he entered the West Towne Pub Sunday afternoon and found a crowd of 200 patrons, buttressed by a throng of journalists from national news media.

Gingrich and his wife, Callista, worked the crowd, signing autographs and shaking hands as they moved from table to table in the packed sports bar.

Despite losing roughly half his support in the polls over the course of the past month, Gingrich told Yahoo News that no adjustments to his approach were needed before Iowa Republicans head to the caucuses on Tuesday night. He clearly took some solace in the roughly 4 in 10 likely caucusgoers who say they could be persuaded to change their minds, according to the latest Des Moines Register poll.

"I don't believe much," Gingrich said when asked about what he needs to change. "Just keep being positive. Keep suggesting good ideas. And keep talking to people."

When Yahoo News pressed him again about any needed tweaks to his strategy after one of the most rapid declines in presidential history from frontrunner to a back-of-the-pack candidate, Gingrich said again he didn't think any changes were needed. But he hinted that he is smarting over the barrage of negative ads that have come his way here.

"No. I don't think so. That's why you have 41 percent undecided after Romney spent $3.5 million in negative ads," he said referring to an ad campaign by the pro-Romney Super PAC, Restore Our Future.
