A few examples.

Ted Cruz does not have the right "temperment" to be President. Look at the way he totally panicked in firing his director of comm. BAD!

Have a good chance to win Texas on Tuesday. Cruz is a nasty guy, not one Senate endorsement and, despite talk, gets nothing done. Loser!

Ted Cruz should be disqualified from his fraudulent win in Iowa. Weak RNC and Republican leadership probably won't let this happen! Sad.

The failing @WSJ Wall Street Journal should fire both its pollster and its Editorial Board. Seldom has a paper been so wrong.Totally biased!

Remember @JebBush wants COMMON CORE (education from D.C.) and is very weak on ILLEGAL IMMIGRATION ("come as act of love"). Not a leader!

Everybody is laughing at Jeb Bush-spent $100 million and is at bottom of pack. A pathetic figure!

I only wish my wonderful father, Fred, gave me $200 million to start my business like lightweight Rubio says. He didn't - total fabrication!

— Donald J. Trump (@realDonaldTrump) February 27, 2016

There are no buyers for the worthless @NYDailyNews but little Mort Zuckerman is frantically looking. It is bleeding red ink - a total loser!

Lightweight Senator Marco Rubio is polling very poorly in Florida. The people can't stand him for missing so many votes - poor work ethic!

— Donald J. Trump (@realDonaldTrump) February 28, 2016

This one is a bit awkward in its wording. But same structure ...

Ted Cruz didn't win Iowa, he stole it. That is why all of the polls were so wrong and why he got far more votes than anticipated. Bad!

In other cases, the third section/stanza is replaced by a verb which is a call to action or threat. But the cadence remains the same.

Make sure you get on the Trump line and are not mislead by the Cruz people. They are bad! BE CAREFUL.

Remember that Marco Rubio is very weak on illegal immigration. South Carolina needs strength as illegals and Syrians pour in. Don't allow it

.@MarkHalperin showed a focus group on @Morning_Joe me using a very bad word. I never said the word, left an open blank. Please apologize!

— Donald J. Trump (@realDonaldTrump) February 11, 2016

The Republican Establishment has been pushing for lightweight Senator Marco Rubio to say anything to "hit" Trump.I signed the pledge-careful

In still other cases, the structure is different. Yet the same triple cadence is unmistakable.

Lightweight Marco Rubio was working hard last night. The problem is, he is a choker, and once a choker, always a choker! Mr. Meltdown.

Mitt Romney, who was one of the dumbest and worst candidates in the history of Republican politics, is now pushing me on tax returns. Dope!

Jeb Bush just got contact lenses and got rid of the glasses. He wants to look cool, but it's far too late. 1% in Nevada!

— Donald J. Trump (@realDonaldTrump) February 17, 2016

Jeb Bush spent more than $40,000,000 in New Hampshire to come in 4 or 5, I spent $3,000,000 to come in 1st. Big difference in capability!

I am looking for an English professor or perhaps a linguist who can perform a more expert analysis on this.
