Larry Sabato bets that a deal will be struck:
If no candidate wins a delegate majority, the brokers may well be the candidates themselves. Their delegates are bound for at least one ballot, and most are personally loyal to the candidate and may follow his lead for multiple ballots, if it comes to that. Romney, Santorum, Gingrich and Paul will have slogged through all 50 states by convention time. Why would they permit someone who slept in his own bed and had regular meals for the past year to swoop in and take the big prize? More likely, perhaps through trusted intermediaries, the four contenders would negotiate a solution — a ticket, platform and prime-time speech schedule.
The alternative is chaos of the first order, with thousands of journalists hovering in Tampa to report every epithet uttered by delegates determined to get their man nominated.
