Rick Santorum seized about as many of Michigan’s GOP delegates as primary winner Mitt Romney, and could end up with more, in a close contest that does little to clarify the muddled presidential race heading into Super Tuesday.

After Romney’s strong win in Arizona and close finish in his native state of Michigan, the GOP field fanned across Ohio, Tennessee and Georgia for the weeklong sprint to Tuesday’s 10 contests. Washington state’s caucuses fall in the middle, on Saturday.

Romney tried to build momentum from his wins, Santorum crowed about his near-miss and Newt Gingrich looked to revive his campaign in the South — where he will battle Santorum for the party’s most conservative voters.
