We noticed Donald Trump says a lot of things twice. He says a lot of things twice.

Political rallies are usually raucous events. That’s just what happens when you bring thousands of like-minded voters together in a theater. Or an arena.

But Donald Trump’s rallies have noticeably been the most rowdy. His events have attracted supporters and protesters in droves, each group as passionate as the other. And Trump himself is the showman-in-chief, using his own brand of stagecraft to fire up his supporters.

Now, he’s even embracing the role of the “anger” candidate – anger about the issues, to be sure, but also anger toward the Obama administration that his supporters share.

Trump is a master of crowd manipulation. His strategy for dealing with hecklers is one good example. His rhetoric, and more specifically his speaking style, is another. Trump, as Fix contributor Barton Swaim wrote a while back, has a habit of punctuating each argument with short, declarative sentences. And then he often repeats them.

He’ll launch into a rant about a particular issue — say, immigration and then conclude by repeating himself: “I want security for this country, okay? I want security.”
