Stephen Colbert has joked that the 2020 Democrats are 'doomed' already after politicians appeared in a video where they revealed their comfort food while on the campaign trail.

Members of the party appear in the clip from the New York Times Candidate Survey and failed to win the funnyman over when asked one of the softer questions about their bid to be nominated as a candidate.

Senator Cory Booker replied: 'When you're vegan, that means lots of veggies on the go.'

Stephen Colbert said on his show Friday Democrats are all 'doomed' after failing to resonate with a US audience when revealing their boring comfort food choice

Cory Booker, John Hickenlooper, Julián Castro, Eric Swalwell and Andrew Yang are some of the politicians who feature in the video of Democrats

More faces from the primaries disappointed with their barely-indulgent answers, as seen on Friday's The Late Show with Stephen Colbert.

Governor John Hickenlooper announced he pops mints and Andrew Yang chomps down on Kind bars.

Candidate Survey questions 1. In an ideal world, would anyone own handguns? 2. Would your focus be improving the Affordable Care Act or replacing it with single payer? 3. Do you think it’s possible for the next president to stop climate change? 4. Do you think Israel meets international standards of human rights? 5. Who is your hero, and why? 6. Would there be American troops in Afghanistan at the end of your first term? 7. How many hours of sleep do you get a night? 8. Do you think illegal immigration is a major problem in the United States? 9. Where would you go on your first international trip as president? 10. Describe the last time you were embarrassed.

More than just few flopped when it came to connecting with the audience over food choice.

But some showed filling their bellies with tasty dishes wasn't how they wound down.

Former housing secretary Julián Castro grinned: 'I don't have a comfort food. I have a comfort drink, which is iced tea.'

Representative Eric Swalwell said: 'My favorite coffee is mocha.'

It prompted Colbert to say what much of the American viewing audience may have been thinking.

'Oh, they are doomed,' he said in between clips of the politicians.

'Mints?! Iced tea? Come on! You're in America! Just say burgers. Or pizza. Or nachos. Or French fries.

'Or just chugging Alfredo sauce straight from the jar!…Comfort food is what you eat because you ran out of Xanax.'

New York Senator Kirsten Gillibrand was more on the CBS host's wavelength however as she admitted she turns to whiskey in times of need.

Other attempts to resonate with voters included revealing their heroes. While several played it safe and went with their wives, in Colbert's eyes the popular answer of Abraham Lincoln was a cop out.

'That's like saying 'My favorite band is The Beatles, my favorite weather is sunny, and my favorite thing to do with my lungs is breathe,' Colbert quipped.

The Times asked 22 Democrats to participate in the survey but they said only Joseph R. Biden Jr. declined to participate 'despite repeated requests since late April'.

All participants were asked to respond to the same questions 'with a simple yes or no, or another terse, direct reply — before explaining their views at greater length'.

The surveys were conducted between March and June and the publication noted that the candidates answered at different points during the completion of the investigation led by Robert Mueller 'so their answers reflected the facts available to them at the time'.

Questions included, 'Do you think President Trump has committed crimes in office?' and 'Do you think illegal immigration is a major problem in the United States?'.
