Donald Trump remains ahead of Jeb Bush in just about every poll — and by wide margins. This has been mostly thanks to Trump's relentless attacks on Bush while on the trail, and to the fact that the media can't stop showing Trump's face at every turn (guilty!).

At every opportunity, Trump has gone for the jugular with Bush, trying to brand the former Florida Governor as boring, bland, and weak.

But on Tuesday, Jeb struck back. With a little help from Stephen Colbert, Jeb put on his best Trump impression to poke fun at his GOP rival's bombastic style.

In an unaired segment for the debut episode of the Late Show with Stephen Colbert, Jeb was asked by Colbert if he'd be open to allowing the talk show host to prep him for next week's GOP debate. 

“You have another debate coming up in about a week on CNN,” Colbert tells Jeb. “I want to prep you for that debate."

When Jeb is asked about his thoughts on Obama's Iran nuclear deal, he gives a response using his own reason and opinions. Then Colbert asks Bush to re-do the question by Trumping it up a bit.

“I will build a wall between the United States and Iran, and make Mexico pay for it!" Bush says, reading off of the teleprompter. “Trucks are strong! I will turn the National Mall into a luxury golf course, and China will respect that! I promise to put Meatloaf on the $10 bill! And give Lil Jon a Cabinet position, which will send the message that this country will never — turn down for what!?”

You can watch the bit below, which begins at the 2:34 mark.

Hours before Bush appeared on the show, Trump had posted a mock-ad on Instagram that showed a woman falling asleep during one of Bush's campaign stops.

Turns out, the woman was a Jeb supporter who showed up to the rally after working a long shift. Bush tweeted out a photo of himself and the sleeping woman in response to Trump's Instagram post.

How voters will react to Jeb making his answers more Trumpier is anyone's guess. But, if polls are to be believed, Bush has a lot of ground to make up.
