Item: Too close to call as voting begins in Florida: Romney-McCain struggle for dominance may be decided in Sunshine State/MSNBC

More Info: "After days of hectic campaigning all over Florida, the Republican presidential contenders could do little but wait for the returns to come in as voters cast their ballots in Tuesday’s primary. Up for grabs: 57 delegates, more than in any previous Republican contest so far this year. Mitt Romney is trying to scuttle the momentum that Sen. John McCain had been gaining in this state after his victory in the Jan. 19 South Carolina primary.

Question: Who'll be the next to drop out of the presidential sweepstakes?
