Santorum hopes voters will focus on Cain's positions as accusations are resolved

Rick Santorum wants voters to pay more attention to fellow presidential contender Herman Cain's positions on the issues.

"If you look at his policy positions, they’re all over the map, and I’m hopeful that as this situation comes to a resolution one way or another that people go back and look at his policies and his positions or his lack thereof or inconsistencies,” the former Republican Pennsylvania senator said according to Radio Iowa. "I think the people of Iowa — they’re going to do their homework."

Santorum's comments come as Cain is battling allegations that he sexually harassed several women while he was president of the National Restaurant Association in 1990s.

On Thursday, Cain sent out a fundraising email saying he was "not deterred" by recent attacks from the media and his opponents.

"The American political establishment has never seen a campaign like ours. It terrifies them," Cain said in the email. "So my opponents are attacking me."
