Rick Santorum suggested the Republican presidential primary would soon become a two-man race where he will measure up well to front-runner Mitt Romney.

“Hopefully after this Tuesday, this will be a two-person race, and we can get down to business of deciding whether we want a conservative or a moderate to go up against Barack Obama,” Santorum said in an interview on Bloomberg Television’s “Political Capital with Al Hunt” airing this weekend.

Santorum, 53, said he expects to win tomorrow’s Kansas caucuses and finish first or second in the March 13 primaries in Alabama and Mississippi, which would set up a head-to-head race against Romney.
