Rick Santorum would consider being vice president to Mitt Romney, a man he's consistently attacked during the campaign, he told the Christian Broadcasting Network's David Brody on Monday.
"Would you even consider it?" Brody asked Santorum, after suggesting he might laugh off the question.
Former Sen. Santorum (R-Pa.) responded that "of course" he would think about it because of the magnitude of the election, calling it the "most important race in our country's history."
"I'll do whatever is necessary to help our country," he said.
If Romney becomes the GOP nominee, it seems unlikely that he would pick Santorum, given the vitriolic attacks the two have exchanged. Last week, Santorum said Romney and the president were so similar on health care that "we might as well stay with what we have," which the Romney campaign claimed was an implication that he would "rather have Barack Obama as president than a Republican."
Santorum made a similar remark on Sunday when he called the former Massachusetts governor the "worst Republican in the country to put up against Barack Obama," again in reference to health care.
Still, Santorum fought back against the idea he would prefer Obama to Romney, cursing at reporter from The New York Times who Santorum said distorted his words on the issue.
In the Monday interview with Brody, Santorum pushed the message that he is more concerned about taking back the White House for Republicans than he is about becoming the president.
"I don't want to be the guy who has to sit with my granddaughter, 20 years from now, and tell stories about an America where people once were free," Santorum said. "I don't want to have that conversation."
