Charles Krauthammer is still hoping Marco Rubio can pull out a primary victory, even though he stumbled so hard in last Saturday's debate. He remains convinced Rubio is the only candidate in the field who can win against the Democrats, despite his consistently robotic performance on the stump and in debates.

In fact, this really is Marco Rubio. Even in his speech Tuesday night, he managed to reassure his audience three times that his robotic debate performance would never happen again, never happen again, never happen again.

Yes, three times in the same paragraph of his speech.

Krauthammer pointed out that Rubio will be dogged by robots all the way into the Southern states, but he forgot to say that Rubio himself has been programmed on repeat.
