Trump is the anti-politician, sent to disrupt the political establishment in Washington D.C. and expose the biased and fake media. It's unusual, but even though he's the incumbent, he still gets to play the role of the outsider and challenger. A lot of people are really offended by his crude demeanor and bully attitude, but he could very easily be re-elected.
The problem with Biden is that he's old, he's listless, and he's wishy washy. Trump is very beatable, but I'll be surprised if Biden wins. Biden is precisely the type of run-of-the-mill career politician that Trump likes to destroy. Biden is similar to Jeb Bush and John Kerry. These types of insipid politicians normally lose presidential elections.
