Where we are post-Nevada GOP is this: Donald Trump has a clear and obvious glide path to the Republican presidential nomination. Stopping him, which still looked plausible as recently as the beginning of this month (with his second-place Iowa results), no longer does.
There is a tendency in the nomination process for voters to move toward candidates who do well: Once a candidate becomes a clear front runner on the basis of voters, a mentality toward joining with the probably winner starts to take over. Historically, this tendency has been visible in both major parties, and likely will recur this year in both.
And most dramatically on the Republican side. The significance of the Nevada result wasn't just Trump's win but the size of it - approaching half of the overall vote in a field of five contestants, three of them well-funded, highly-visible and strongly-supported. As many have said elsewhere, if the front runner were a conventional politician instead of Donald Trump, the contest would more or less be called over already. The infamous and garbagey Drudge Report (which has been in Trump's pocket for months) has "called" him the Republican nominee, and it has to be said in this case there's good reason for saying so.
Little time remains for anyone else to figure out a way to solve the Trump problem. Next Tuesday, March 1, is "super Tuesday," when not one but a whole mass of states - Alabama, Alaska, Arkansas, Colorado, Georgia, Massachusetts, Minnesota, Oklahoma, Tennessee, Texas, Vermont, Virginia, and Wyoming - make their decisions. They will make those decisions in large part on the basis of national perceptions, and presumably for some of the same reasons the states voting so far have done so. Trump is by far best positioned to present himself as the nominee-in-waiting, will doubtless be regularly described as such between here and there, and he stands a good chance of sweeping nearly all those states. (The biggest exception could be Texas, but if Trump wins there, which seems plausible, he could destroy Ted Cruz' candidacy.) And if he does sweep those states, his delegate lead could become hard for anyone else to catch up to.
The Republican contest isn't quite yet a done deal, but this time a week from now, barring a case of late concerns or buyer remorsem it might be. - rs
