Bill Maher gives withering comparison to Biden during his car crash debate with Trump - as the comic brands Joe with hilarious new Secret Service name

Bill Maher ripped Joe Biden's performance in his debate with Trump, joking he'd 'seen beauty pageant contestants answer questions better' than the president.

The comedian dug into the president's disastrous debate in his opening monologue for his Max show, Real Time, on Friday.

Bombshell new polling revealed even fewer voters believe Biden is is mentally up to the task of being president for another four years after he struggled to get through debate night.

Maher has regularly criticized Biden's chances at re-election, often declaring his age to be the biggest problem. 

'I don't want to say he s**t the bed, but his new Secret Service name is Amber Heard,' Maher said.

He was referencing Johnny Depp's testimony in which he claimed his ex-wife defecated in their bed at their Los Angeles penthouse after an argument the night before her 30th birthday in February 2016.

'Did you see the debate? In case you missed it don't worry so did one of the contestants,' said Maher.

'I mean Trump told lie after lie after lie. He never would have gotten away with that if Joe Biden was there.

'You know Joe, he famously loves trains but apparently not of thought.'

Earlier in June, Maher declared Biden's new immigration policy would cost him the presidency after he issued an executive action that limited the number of migrants who can arrive at the border and claim asylum to 2,500 per day.

Maher said: 'If Biden loses this election, it's going to be because of two things: He's old… and immigration.

'I mean, just on a political level, I don't think they could have handled it worse.'

Biden attempted to manage the fallout from his dismal debate performance at a rally in Raleigh, North Carolina, on Friday.

'I know I'm not a young man. To state the obvious,' the president said, standing alongside First Lady Jill Biden, who wore a Christian Siriano dress covered with word 'vote.'

'But I know what I know - I know how to tell the truth. I know right from wrong. And I know how to do this job. I know how to get things done,' the president argued.

He then swore to the people in the audience that he was still ideally suited for the nomination.

'I give you my word as a Biden. I would not be running again if I didn't believe with all my heart and soul that I could do this job.' 

Biden tried clean up many of the arguments he attempted to make on the debate stage against his Republican opponent.

'I don't know what you did last night but I spent 90 minutes on a stage debating a guy who has the morals of an alley cat,' Biden said.

'Did you see Trump last night? I guess he set a new record - I mean this sincerely - for the number of lies told in a single debate,' the president continued.

At the end of his speech, Biden suggested that the rally appearance was the beginning of his post-debate redemption arc.

'I know what millions of Americans know - when you get knocked down you get back up.'

For his part, Trump told a crowd of supporters at rally stage in Virginia on Friday that Biden 'didn't know what the hell he was doing' during the debate.

'He got the debate rules he wanted, he got the date he wanted, at the network he wanted with the [moderators] he wanted.

'No amount of rest or rigging could defend his atrocious record.'
