The many people who have wanted the Republican presidential campaign to boil down to a manageable number have got what they want - almost.
There's now three, nearly. Five, for the moment.
Because the catch is, John Kasich and Ben Carson are still in.
Neither of them will be the nominee, and probably they are well aware of that. But neither is inclined to leave. Both seem to be doing well enough in fundraising - and they occupy distinctive enough niches - that they can keep on offering messages for a while. (Kasich seems to want to stay in until his home state of Ohio votes.) In the process, they will keep on typing up blocks of votes. Small blocks, but possibly significant anyway.
As it stands, Donald Trump seems well positioned for the nomination. If as polling indicates he wins Nevada in tomorrow's caucuses, his track record will be three wins and (in the distant Iowa past) a second place, enough to position him as a clear frontrunner and create a bandwagon effect for the massive SEC primary on March 1, barely a week from now. If the national narrative going into that is that Trump is running well ahead of everyone else, he will become very hard to stop.
If anyone does stop him, that would have to be Ted Cruz or Marco Rubio, who more or less share a second-place spot. But aside from a Cruz win in Texas and Rubio in Florida (and Trump could very well win both of those states anyway), it's getting ever harder to see where they break through and actually beat the Donald.
Time is getting short. - rs
