It has been nine months since Jon Stewart departed the nation's screens as The Daily Show host, but he has still made time to share his candid thoughts on Republican frontrunner Donald Trump.

At the University of Chicago Institute of Politics, Stewart told David Axelrod he joked that he wasn't sure if Trump was even eligible for the presidential nomination. 'I'm not here to be politically incorrect, if they're referred to as man-baby Americans… but he is a man-baby,'

'I'm not a constitutional scholar, so I can't necessarily say, but are you eligible to run if you are a man-baby, or a baby-man?' he asked, adding: 'He has the physical countenance of a man and a baby's temperament and hands.'

Speaking out: 'I'm not a constitutional scholar, so I can't necessarily say, but are you eligible to run if you are a man-baby, or a baby-man?' former Daily Show host Jon Stewart joked about Donald Trump

A lot on his mind: Stewart went on to describe Trump as thin-skinned and an 'unrepentant, narcissistic a******.' He mocked Trump's slogan. 'When was America great? What is this time that he speaks of? '81 to '82?

Stewart went on to describe Trump as an 'unrepentant narcissistic a******' before raising the question of the time period Trump is speaking of them he says he wants to 'Make America Great Again.'

'When was America great?,' Stewart asked in typical fashion, 'What is this time that he speaks of? '81 to '82? Like what are we talking about? And who took your country away from you?'

During the interview, the former talk show host also described Trump as thin-skinned for the presidency, referencing a famous 2013 Twitter war as evidence.

'We made fun of him. And I think we referred to him as a boiled ham in a wig, and so he tweeted at me. Because, as you know, great leaders tweet late at night, as I'm sure you remember Lincoln's Gettysburg tweetstorm,' Stewart said.

Stewart argued that Trump's criticism that America is now weak and sensitive due to political correctness is ridiculous. He then went on to say he thought Trump was hypocritical, blasting him for ridiculing his rivals and minorities.

'If Trump really wants to engage a politically incorrect debate', Stewart said. 'He should tell voters, 'The problems in this country are not because of Mexicans and Muslims.'

Taking aim: Stewart added that Clinton is going to be in 'big trouble' if she doesn't find a way to convince voters of her 'authenticity.'

Stewart later added that 'at this point, I would vote for Mr. T over Donald Trump.'

Stewart pinned some of the blame for Trump's rise on what he described as the failure of Democrats to transform the public sector into a more dynamic actor.

'The door is open to an a****** like Donald Trump because the Democrats haven't done enough to show people that government, that can be effective for people, can be efficient for people,' he said. 'And if you can't do that, then you've lost the right to make that change and someone's going to come in and demagogue you.'

The iconic former Comedy Central host also had choice words for Hillary Clinton, calling her a 'very bright woman without the courage of her convictions because I'm not even sure what they are'.

'When I watch her campaign, it reminds me of... Magic Johnson's talk show.'

The reference is to the NBA Hall of Famer's short-lived TV show which featured a host ill-suited to the medium but eager to be whatever people wanted him to be. 'It never seemed authentic and real to his personality,' Stewart added.

Future project: Stewart says he has no plans to return to TV but hinted at plans to make short, viral-video political cartoons starting in September

He added that Clinton is going to be in 'big trouble' if she doesn't find a way to convince voters of her 'authenticity.'

Stewart had some harsh words for the candidates' political parties as well. While the Republican Party's 'sole purpose is to freeze the government and to not fix any of the problems that are associated with it,' the Democratic Party has failed to make government more efficient and opened the door to a Trump candidacy, he said.

He also criticized the media's coverage of the 2016 campaigns, saying the relationship between journalists and politicians is no longer one of 'predator and prey' but of remora and shark.

Stewart said 24-hour networks amplify voices that are 'the most conflict-oriented, the most extreme', and Trump's strategy has been the same as Jonny Fairplay's on Survivor.

Pressed by Axelrod on the possibility of a return to the political sphere by November, Stewart replied by quipping, 'I mean, I'll vote…'
