CNN — Former Republican presidential candidate Rick Santorum said in a Monday interview with an Iowa radio station that his party's presumptive nominee hasn't been in touch with his one-time rival as part of the vice presidential vetting process.
"You'd have to ask (former Massachusetts) Governor Romney who he's considering," Santorum said, but "I haven't been in touch with the Romney campaign, so I suspect that we're not under active consideration at this point."
Santorum said selecting the No. 2 is an "important decision."
"I suspect it will be a solid conservative and someone that we can get excited about," he told Radio Iowa.
Santorum won the Iowa lead-off caucuses in January and came closest to Romney in the race for the Republican nomination. Santorum won 261 delegates before dropping out in mid-April as the delegate math appeared stacked against him. He later said other factors, including the health of his youngest daughter, played a role.
He has planned a series of campaign and meet-and-greet events in the first-in-the-nation caucus state through Thursday.
Echoing comments made by other possible vice presidential candidates, Santorum told Radio Iowa that he wants "to do whatever we can to be helpful to Governor Romney" and sees himself campaigning for other Republicans.
"If my campaigning will be of help to candidates, conservatives who want to come to Washington, D.C., and want to shake things up and really return this country back to the governing principles that made it the greatest country in the history of the world, then I'll be active and involved," he said. "At least a lot of folks are calling and asking for help, so that's a good sign that maybe we can be helpful there."
Asked whether Romney was properly "prosecuting" the campaign against President Barack Obama, Santorum did not offer a clear opinion of Romney's campaign style, but said that the driving "issue in this race has to be Obama."
"Right now, there's just a barrage of back and forth," he said, "and I'm not too sure a whole lot of people are paying a whole lot of attention to it at this point."
