"He's 6'2," Marco Rubio said of Donald Trump Sunday night, "which is why I don't understand why he has hands the size of someone who's 5'2. You know what they say about men with small hands."

It was perhaps the most explicit small-penis joke in the history of presidential politics.

"I liked him until he got down in the mud with Trump," Paul Eveland told me before the Rubio rally. While his wife, Ceci, is behind Rubio, Paul is undecided. "I liked him until he got down in the mud with Trump." Ceci granted that point: "It's disrespectful to the office."

Donald Lawrence calls Trump "a damn clown. I used to watch people like that on cartoons." But Lawrence, who was dragged to the rally by his wife, a Marco fan, doesn't appreciate Rubio's style of fighting the clown Trump. "It kinda made them look like they were a big joke," said Lawrence. "You get somebody who wants to joke around, you wonder who good a President they'll be."
