Sure, right now, the polling indicates that either of them would beat Trump in a head-to-head contest. So it makes a surface level amount of sense that they would try to make sure they are the last candidate standing against Trump, however long that takes. What they are ignoring is that the longer they allow Trump to prance around virtually unscathed, allowing Trump to rack up huge wins while they battle each other for second place, the less likely it is going to remain true that they will defeat Trump in a head to head matchup. Republican voters are still suckers for the siren call of inevitability.

Both Cruz and Rubio right now sound like a couple of kids in the backseat of a car bickering and every time someone suggests that they ought to stop and focus on Trump (or something else entirely), they begin the pointless and childish cry of “He started it!” And then the other says, “No, HE started it!” and then that becomes its own argument.

I do not care. I don’t know anyone else who really does. I am sick and tired of both of these guys rolling the dice on the chances that by the time they sort out their own argument, Donald Trump won’t already be invincible. You know who is shaming both of these guys right now? Jeb Bush. You know why he experienced a bump after last Saturday’s debate? Because people finally saw someone who was willing to confront and stand up to Trump. You know why Kasich was able to finish second in New Hampshire? Because a lot of voters were sick of it too and transferred it onto a blank slate.
