Donald Trump is doing what no candidate in Iowa should be doing today -- holding rallies and speaking to people and getting them all stirred up.

Clearly Trump is clueless about what wins the Iowa caucus -- turning out the vote. Because if he had a clue, he wouldn't be holding rallies on caucus day, and MSNBC wouldn't be covering his thug life for the world to see.

But he is, and during a rally today, he called on his brownshirt brigade to "beat the crap" out of anyone who might be throwing a tomato at him.

"There may be somebody with tomatoes in the audience," Trump declared.

As the crowd cheered him on, he said, "So if you see somebody getting ready to throw a tomato, knock the crap out of them, would you, seriously."

He added, "Just knock the hell -- I promise you I will pay for the legal fees, I promise."

We are seriously entering territory here where we should not go. When a leading candidate for his party's nomination starts calling for the crowd to "knock the crap" out of someone, well, I think you get the idea.

Because here's the reality. There are people at that rally who would be glad to "knock the hell" out of someone just because they hate liberals that much. And they are bloodthirsty right now. Seriously hungry for some progressive blood.

Thanks for that, Donald.
