This Donald Trump is full of bologna.

The presidential hopeful is already making his mark in Washington, DC — with a new sandwich named after him at an area diner.

The sammy includes a pound of bologna with lettuce, tomato and mayo on toasted white bread

American City Diner owner Jeffrey Gilderhorn put the Trump sandwich on the menu just four days ago — and he’s already gone through at least 20 pounds of bologna.

It’s been such a hit that is such a hit that he’s already doubled the price from $6.95 to $12.95.

“Normally, we don’t even carry bologna,” he said.

Each sandwich is paired with a card that reads “Big enough to fit in Trump’s big mouth.”

Locals have been lining up for photos of the diner’s neon marquee, which says “The Trump Sandwich Full of Bologna” in red lettering.

“People tell me they don’t like Trump, but they like the sign,” Gilderhorn said.

Gilderhorn said he’s “not a fan” of the business mogul — but certainly doesn’t mind cashing in on his popularity.

And he doesn’t expect to see The Donald chowing down on his namesake any time soon.

“I don’t think Trump is going to worry about our sandwiches,” he said. “He’s got a lot of other things to worry about.”
