Picking candidates that are so defective that they can actually make Donald Trump look good.
In the case of Biden mentally coherent and sharp, in the case of Hillary, likable and man of the people. The Democratic party doesn't even prioritize the Democratic party anymore. It's just favoring a select group of insiders that are well aligned with lobbyists and have backroom power within the party. Trump should be one of the easiest people to beat. He doesn't really win anything, it's just that both the Republicans and Democrats have shown an amazing capacity to lose to him and I think it all comes out of the one and only principle that both party leadership have which is cronyism. I have never in my life seen both parties so out of touch with the people, and you can see that in the disapproval ratings. This is The logical end result of politics based off of the lesser of two evils compromises.
