READ: Part 2: Former Vice President Dan Quayle talks President Trump, 2020 election
President Donald Trump burst onto the political scene in 2015. Since then, many have suggested the party has drastically changed.
We took that question to former Vice President Dan Quayle.
"The party has clearly changed," he explains. "Both parties have changed. It seems that many people that are elected today and go to Washington don't want to necessarily get things done."
And which party comes out on top in November is still anyone's guess four months before the general election. Vice President Quayle supported President Trump in 2016 and says he will get his vote again this year.
But what about his chances against the man who once held the same office he did -- former Vice President Joe Biden?
"If he stays as he should be and runs as the Joe Biden that I know, he's beatable but he will have a good chance of getting elected. But I don't think he'll stay here. I think he's moving way to the left...I've known Joe Biden for years. I served with him in the Senate. He's a good guy. I like him. But I'm not going to be voting for him."
In just the past few months, President Trump has been hit with a number of controversies, like his handling of the Black Lives Matter movement. Vice President Quayle says the movement has been a "significant force in American politics," but says he also wants to know what's next.
"Defunding the police? I'm not so sure that's a good thing. Maybe we should reform the police? Reform the police unions that allowed this guy to have 18 different charges against him, a couple going into arbitration and he was still there."
And what about Attorney General William Barr? Barr served under President George H.W. Bush. Democrats have accused Barr of acting more like the President's personal attorney.
"He knows what the role of an Attorney General is. He knows the boundaries that the Attorney General has with the President and he is not going to cross that line. I can assure you that."
But what about the firing of the U.S. Attorney for the Southern District of New York -- the same office that prosecuted Michael Cohen and Rudy Guiliani's associates?
"I'm not sure about the timing of it. I think that might have been a slight miscalculation. Doing it four months before the election, I might have waited."
ABC15's Nick Ciletti asked what Vice President Quayle's advice would be for President Trump if he were to be re-elected in November.
"Well, he needs to start talking about what he's going to do in 2021 and beyond. What's he going to do for the next four years? My advice would be to lay off the Twitter but that's not going to happen. So why give the advice if it's not going to happen? But I'll give it anyway."
And despite everything 2020 has thrown our way, Vice President Quayle thinks that the election will come down to one single factor.
"You need leadership. That's what's lacking today across the board - leadership. A strategy for bringing us together, how we are going to follow the strong leadership. And the person who articulates that the best will be the next President of the United States."
