So there is basically no precedent for losing a bunch of early primaries and carrying on, let alone winning the nomination. Now, let’s look at some of Rubio’s numbers.

In Iowa today, he’s a distant fourth, with around 12 percent to Donald Trump’s 27 percent. New Hampshire is the one early state where he’s not off the boards completely, but even there he’s not in great shape: He’s second with 12.5 percent to Trump’s 26 percent. In South Carolina, he’s basically tied for third with Cruz, but again, both have less than half of Trump’s 29 percent. Nevada is less obsessively polled than the first three, but the latest one, from mid-October, has Trump miles ahead with 38 percent. Rubio is at 7.

So that’s the big four. If anything, after that, it gets worse for Rubio. Here is the official GOP primary schedule. Here is the most comprehensive list of polling from every state that I’ve seen. Match them up against each other and see for yourself. But because I’m a nice guy, I’ll give you a little taste for free.

After Nevada comes the big date of March 1, Super Tuesday, when 12 states have primaries or caucuses. Most of the big ones are in the South—Texas, Georgia, Virginia. In Georgia, Rubio is right now a distant fourth. He’s also a distant fourth in Texas, where Trump and Cruz are tied for first. In Virginia, things look better: He’s only a distant third.
