OSHKOSH, Wis. - Newt Gingrich vowed today to remain in the GOP presidential race until Mitt Romney "gets the majority" of the delegates.

Gingrich made the comment to reporters as he was working the rope line at the University of Wisconsin - Oshkosh.

"I think we're working until Romney gets the majority. In the meantime he has to earn the majority," he said.  "I'm the only person in the race to pass a federal budget four times, and the only person to organize a national majority in 1994 and '96. I think beating Obama is important."

Asked what he and Romney discussed in their closed-door New Orleans meeting last Friday, Gingrich said: "Same thing I talked to Santorum about… beating Obama."

Gingrich did not mention the recall of Wisconsin Gov. Scott Walker in his address here. Mitt Romney and Rick Santorum have supported the governor's quest to hold onto his job after spearheading reforms affecting the state's unionized workers.

His speech was the same he's given the past three days at other colleges, about harnessing American innovation.
