Obama's vicious attack on Trump suggesting he wears adult diapers and mocking him for hawking sneakers and Bibles as 2024 polls tighten

Former President Barack Obama viciously took down former President Donald Trump during his first solo outing on the campaign trail in support of Vice President Kamala Harris. 

Speaking at the University of Pittsburgh Thursday night, Obama hinted that he believed that the 78-year-old Trump wore adult diapers. 

Obama, 63, recalled that he couldn't believe how expensive diapers were when he became a parent. 'Do you think Donald Trump ever changed a diaper?' he mused. 

'His own!' yelled back an audience member. 

'I almost said that, but I decided I should not say it,' Obama said with a laugh.  

He also went after Trump for hawking products amid his presidential run. 

Obama called out Trump for his 'tweeting in all caps' and his 'rantings and ravings about crazy conspiracy theories.'

'You've got the two hours speeches, word salad, it's like Fidel Castro, like on and on; constant attempts to sell you stuff,' the Democrat went on.

'Who does that?' he mused. 'He sells you gold sneakers and a 100,000 watch and most recently a Trump Bible.'

'He wants you to buy the word of God, Donald Trump edition, his name next to Matthew and Luke,' Obama said. 'If you saw it on Saturday Night Live, you’d say no that’s going too far…It's crazy.' 

Obama started out his 45-minute speech by saying that he got why people were frustrated in the current political climate. 

Swing state polls show the 2024 race to be extremely tight.  

'Let's face us, we've been through a lot these last few years,' he conceded. 

He mentioned the pandemic and the overall economic woes of the country, especially being felt by 'working people.' 

'So I get why people are looking to shake things up,' he said. 'I am the hopey-changey guy.'

'What I can't understand why anybody would think that Donald Trump will shake things up in a way that is good for you Pennsylvania,' he continued. 'Because there is absolutely no evidence that this man thinks about anybody but himself.' 

Later he made a similar point, pointing to the January 6 Capitol attack. 

'If Donald Trump doesn't care that a mob might attack his own vice president, do you think he cares about you?' the ex-president asked. 

Throughout his speech Obama asked the audience if Trump did everyday things.

He commented on how Democratic vice presidential nominee, Minnesota Gov. Tim Walz, could take a truck apart.

'Do you Donald Trump has ever changed a tire in his life?' the ex-president said chuckling. 'I'm just trying to picture it.'

The diaper comment was made in a similar manner. 

Obama also tried to shore Harris up in areas where polling shows that she's weak - including the economy and immigration. 

The Democratic ex-president remarked how Trump gets credit for a good economy during his term. 

'Yeah, it was pretty good, because it was my economy,' Obama boasted. 'It wasn't something he did.'  

'I spent eight years cleaning up the mess that the Republicans left me,' Obama added. 

Obama took office in 2009 directly after a financial crash due to predatory lending  to borrowers with low incomes for homes. 

Trump has made immigration his top issue in 2024 - as he did when he first ran for the White House eight years ago. 

'When I hear Donald Trump talking, I've got one question. As I recall, Donald Trump was four years. And if rounding up and deporting millions of desperate people and building the beautiful wall - and it didn't matter whether some of those people you rounded up were women and children - if that is the answer to everything, well why didn't you solve the problem?' 

Opening acts for Obama included a number of Pennsylvania Democrats, including the state's popular Gov. Josh Shapiro, a finalist to be Harris' running mate. 

'I've got a message for Donald Trump: Stop s***-talking America,' a fired-up Shapiro said. 'He's so unfit to lead,' he scoffed, versus Harris, 'someone who gives a damn.' 

Polling ahead of Obama's appearance in Pittsburgh found that he's a more popular figure than Harris in Pennsylvania. 

The ex-president is also more popular than Trump. 

Emerson College polling done with The Hill found that 55 percent of Pennsylvanians view Obama positively compared to 48 percent for Harris and 50 percent for Trump. 

Obama also received higher marks than the two presidential hopefuls in the key swing states of Arizona, Georgia, Nevada, North Carolina, Wisconsin and Michigan - meaning he could be a useful voice all over the battlegrounds. 

But Pennsylvania - nicknamed the keystone state - will likely be the key to either Harris or Trump's victory on November 5, as the path to 270 electoral votes becomes very unlikely if a candidate loses it. 

University of Pittsburgh students attending the event told DailyMail.com that the 63-year-old former president was still hip. 

'Absolutely. 1,000 percent. I just think he's so influential and so inspirational. The first black president - that just means a lot to me specifically,' said 19-year-old Pitt sophomore Ava Nicholas. 

She echoed that Obama could '1,000 percent' inspire young people to vote for Harris. 

'Just the amount of influence he still has, even being out of the presidency,' Nicholas continued. 

Fellow Pitt sophomore Jade Davis, 20, spoke of the 'big impact' Obama had on her and her peers as the first black president and first biracial president 'even if some of us either weren't born yet or were really young,' she commented. '

'I feel like that's something like, even though I was little, that I just won't be able to forget,' Davis said. 

She answered in the affirmative when asked if Obama was considered 'cool.' 

'Yes and I feel like he's just a nice person, that's what sets him apart from other politicians,' Davis said. 'He's very personable. Other ones they can be a little bit stiff or you can't really get to know them on like a personal level, but I feel like he's very open.' 

'He even has a book about his life,' she added.  

However, in a sign that Harris could not get the margins she needs in Pennsylvania over the war in Gaza, the young people DailyMail.com also knew peers who were refusing to vote over the Biden administration's support of Israel. 

'I do know of a lot of people who are choosing not to vote at all for Kamala Harris because of, like the complicitness of the Biden administration,' Nicholas acknowledged, saying she believed this was 'dangerous.' 

'I feel like any vote not for Kamala Harris and Tim Walz at this point is a vote for Donald Trump,' Nicholas said. 

Nicholas said she believed potential non-voters could be moved into Harris' column. 

'I think that it's definitely a movable position,' Nicholas said. 

Davis said it might help 'if Kamala made more of a stance on it, but at this point she may not.' 

Harris has tried to split the difference on Gaza, saying she continues to support Israel's right to defend itself, but condemning the killing of Palestinian civilians. 

The pick of Walz was seen as a move to sweeten her candidacy with the pro-Palestinian left, but groups like Uncommitted - which started in the swing state of Michigan - have, so far, refused to endorse her.
