If you’re going to program a computer to generate Trumpspeak, count the number of times the average person uses first singular pronouns: I, me, my, mine. And then multiply that rate by ten.
Top five:
I

me
At the risk of ruining the joke, I took Trump’s Economic Speech in Detroit, and cataloged the words that were used five or more times. All words in lower case. Transcript from here:
I put some words in red for various reasons. “I” beats “Hillary”, which beats every other substantive noun other than jobs. American is the most popular adjective and substantive word.

Woulda been quicker to use a wordcloud: Trump's Detroit Speech on Economics – Word cloud – WordItOut
I had a couple, but then I recalled the McCarthy/Hellman feud and I think McCarthy’s quip says it best:
“Every word she writes is a lie, including ‘and’ and ‘the.’”
“You tell me”.
Sarcastic.
But not so sarcastic.
“Let me tell you”
“Extreme vetting”
"Can you believe it? "
Another very common version of this is “I’m hearing” or “I heard”, as in “I hear the unemployment rate may be as high as 42%”. 
“Absolutely”
“By the way”
Choke, choked, choke artist
“Friend of mine”
“Get him out a here!”
“I hate to tell you”
“I made a lotta money”
“He’s a total joke [or jerk].”
“Nobody knows”
“…like a dog”
“I never met 'im”
“You’ve never seen anything like it”
“There no question about it”
“There’s something going on…”
“Thousands and thousands”
“… is a total mess”
Total, totally
"I said ‘Wow’ "
“Take a look”
Disgrace
Is that a still of this guy? (caterpillar)
Has anyone counted how often he says “I don’t know”? Has anyone said to him “Isn’t it about time you actually, you know, looked it up?”
There’s something going on…
So, is this a drinking game for the debates?
Have you priced a liver transplant lately?
Crooked Hillary
Best
Tremendous
Class/Classy
Quality
Stupid
Moron
“The” when used in front of a racial group “The Blacks”, “The Hispanics”, “The Asians”
Always followed by “love me.”
