And since timing is important
From Jon Ralston [UPDATED, 11/5/16, 5 PM]
Let me remind you of the math: Trump would need to be holding 90 percent of the GOP base and Clinton would have to be losing 15-20 percent of hers and he would have to be winning indies for him to be competitive. Let me be clear: None of those things are likely.
The Reid machine and the Hillary campaign did not spend two weeks turning out crossover voters. They know what they are doing. Trump is probably down 12-15 points in Clark County and 65-70,000 votes. You can't make that up unless Election Day turnout is so large and so GOP-heavy that he could. And with two-thirds of the vote in, and with Democrats not simply willing to roll over and not rev up the machine on Election Day, that ain't happening.
