Gingrich has embraced the role of spoiler whose goal is to thwart Romney's chances of winning the 1,144 delegates needed to clinch the nomination before August, and instead attempt to force an open convention. There, Gingrich seems to believe he could capture the nomination.
"In a setting where I have grave doubts about Governor Romney's ability to win the general election, I have a citizen's duty to try to help us get to an open convention," Gingrich told NPR radio last week.
The presence of Callista beside her husband at almost every stop in the campaign has done little to help Gingrich. A Public Policy Polling survey last week showed only 18 percent of people view her favorably, versus the 44 percent who see the former congressional aide as unfavorable.
Gingrich, 68, has acknowledged having an affair with Callista, 46, while he was married to his second wife.
"This is clearly still an open race. So, on behalf of the more than 176,000 Americans who have donated to Newt 2012, I will carry our solution-oriented campaign to Tampa," Gingrich said after the Louisiana results were in.
