Billionaire Mark Cuban knows how to read other billionaires. And he sees a killer in Donald Trump.

Cuban took to his site Cyber Dust to analyze the presidential race and the Republican front runner.

First. I like him. Will I vote for him? Way too early to decide.

Now here is what you need to know about DJT:

1. His most important word is Killer.

If you are not a killer, he doesn’t respect you. If you are a smart killer, you have used knowledge, effort and something that makes you special to accomplish what most dream of.

He does not think any of the other candidates in either party is a killer. Which is why he has no trouble criticizing them.

“He knows the best most can do is talk about their political accomplishments which no potential voter that is paying attention now respects,” according to Cuban. “If our politicians approvals are at all time lows, saying u are great at is plays right into his hands.”

Cuban believes Trump’s “greatest weakness” is technology and offered some advice to his competitors.

“If you want to beat Donald in the summer and winter you have to be a smart killer that can go toe to toe with him and crush him with his kryptonite.

“His kryptonite is technology. He doesn’t understand it.”

The Dallas Mavericks owner then said his fellow billionaire is lucky he’s not running.

“I would toy with him,” Cuban wrote, adding a smiley face.

“There is no one running that can stand up to him. He knows it. That’s why he isn’t leaving anytime soon. He smells the kill,” Cuban said, the Dallas Morning News reports.

“I said pay attention to how DJT says things more than what he says. People hate politicians. Donald fashioned himself a Killer of political correctness. A Killer of politics as usual. A killer of those, both real and imagined who would threaten American’s future,” Cuban wrote.

He predicts Trump’s support is going to grow.

“Donald Trump has changed politics. We want to vote for a killer of those who threaten our future. He has sold his way to that position. I think even those who hate him now, when the number of candidates thin, may come around and realize that he may be a better alternative and vote for him, even if they don’t like him.”
