Mark Cuban reveals if he thinks Kamala Harris can win a critical swing state as tells crowd why Trump is the 'biggest loser'

Billionaire entrepreneur Mark Cuban told DailyMail.com Wednesday that Vice President Kamala Harris can 'absolutely' win his home state of Pennsylvania. 

Cuban was on hand Wednesday as Harris laid out her economic vision at an invite-only event at Carnegie Mellon University in Pittsburgh. 

The Shark Tank star said he would be willing to do 'whatever I can' to get Harris over the finish line in the must-win swing state. 

'I'm from Pittsburgh, so meeting with and talking to a bunch of people and, you know, taking pictures, signing autographs and doing what I need to do,' Cuban said of his role boosting the Democratic nominee over former President Donald Trump.

In her remarks in the Steel City, Harris hit Trump on his manufacturing record, calling him 'one of the biggest losers ever.' 

'Now look, my opponent Donald Trump - well he makes big promises on manufacturing,' Harris said. 

'Just yesterday Trump promised to bring back manufacturing jobs,' the Democrat continued. 'If that sounds familiar it should.'

'In 2016 he made the same promise about the Carrier plant in Indianapolis,' Harris said. 

She pointed out how Carrier then offshored hundreds of jobs to Mexico during Trump's term.  

'And it wasn't just there, on Trump's watch offshoring went up and manufacturing jobs went down across our country and across our economy, all told, almost 200,000 manufacturing jobs were lost during his presidency starting before the pandemic hit,' Harris went on. 

'Making Trump one of the biggest losers ever on manufacturing,' she said to laughs and cheers. 

Trump told a crowd in Savannah Tuesday that he would force foreign companies to manufacture products in the U.S. by threatening them with tariffs. 

Harris' 40-minute economic address spoke to both Pittsburgh's past - as a manufacturing powerhouse - and its tech-heavy present, with CMU an innovator in areas like robotics. 

She spoke about bolstering American manufacturing and helping start-ups get access to capital, hitting Trump on hurting small businesses as well. 

The Harris campaign's goal is to try to chip away some of Trump's polling edge on the economy, which voters often list as their No. 1 issue this election cycle, especially with inflation hurting the average American's pocketbook. 

'I have pledged that building a strong middle class will be the defining goal of my presidency,' she said.  

As a Harris campaign surrogate, Cuban has been trying to push that it's Harris - not Trump - who has a plan. 

'When you talk to her staff about putting together a policy, they literally dig in and try to understand it,' Cuban said. 'And when you do that like a real business, you're not just going to be impetuous about everything that you're going to say.' 

Cuban said Wednesday that he believes Trump's advantage on the economy is 'declining.' 

'I mean people are realizing that having a well thought-out plan is a whole lot better than someone who just talks off the tushy,' he told DailyMail.com.
