Republican candidate Rick Santorum is gunning for a victory in at least one of the three states holding presidential nominating contests on Tuesday in an attempt to slow down front-runner Mitt Romney and revive his fading White House hopes.
The former U.S. senator from Pennsylvania narrowly won Iowa on Jan. 3 but his drive to become the main conservative alternative to the more moderate Romney has not played out the way he had hoped. He has had weak showings in New Hampshire, South Carolina, Florida and Nevada.
