Washington, Dec. 8 (ANI): If Sarah Palin seeks to run for 2012 presidential elections, she would have "some explaining" to do, former Republican Senator Rick Santorum has said.

"She's done a lot to draw attention to herself that's positive," Politico quoted Santorum, as saying.

"She has done some things that, you know, certainly are going to cause her to have to do some explaining if she runs for president," he added.

During an interview on ABC's "Top Line", Santorum said: "But right now I think she's on a roll, she's having a good time, she's having an impact.

"If you're sitting here out of office, the thing you want to do is have an impact on the direction of the country right now, if you're not governing things. And she's having an impact," he continued.

On his own 2012 presidential ambitions, Santorum said that he's "absolutely taking a look" at building a presidential campaign.

"But look, I'm doing it in the context that right now, there [are] very important matters and I want to weigh into those matters as to what the Republican Party stands for in 2010," he said.

"I think I've been very clear that, you know, we need to stand foursquare on the traditional values," he added. (ANI)
