Sorry, but "Everyone Loves Donald" was contracted to run another 6 years at this rate, but is up for contract renewal in 2020 at least, so we'll see.
Hope they pick someone who can run against Trump next time and don't get sucked back into the "anyone could beat Trump" mindset. That's more a human failing than a Democrat-specific one however: quickly forgetting the recent past in self-serving ways is the human condition.
I think Sanders was better for one main reason: he appealed to the Left, but he also appealed to the Libertarians, who tend to flip-flop between the left and right sides and see themselves as outside of the spectrum. You can win with Liberals+Libertarians, but not with just doubling-down on hardcore "big L" Liberal values, even with a more "respectable" center left candidate. You need to throw some carrots out for other people, too. And if you're not willing to make concessions that conservatives will like, then you need to find someone else to ally with, and that has to be the libertarian-minded people. But the big problem in this election cycle is that a lot of younger centrist types are being branded as alt-right no matter how tenuous their actual support for any "right wing" stuff is. This is openly driving a lot of younger voters away, but the argument is that they're "not needed". Good luck with that, honestly, since I don't want to see Trump re-elected as much as anyone, but I have a bad feeling there.
e.g. I'd argue that both sides in fact have a complex relationship with the "blue collar" masses, since both established sides of politics are run by people who are higher-educated and mix in limited circles which have a lot of group-think. e.g. just bouncing policy off your facebook friends and finding that they all agree it sounds good isn't a good indication of how those ideas will go down with other groups. This is why I like Jonothan Haidt's stuff on the matter of getting liberals and conservatives to talk to each other. He's more thoughtful and balanced that Peterson and less confrontational about it (Peterson being so confrontational in attitude is in fact hypocrisy, given what he claims other should be like: less confrontational and opinionated). By looking at Jonothan Haidt's stuff (and other thinkers like Steven Pinker have good suggestions too) you can see how the whole language system and worldview / thought process of conservatives vs liberals are completely different, self-contained and self-consistent systems. e.g. one of the common mistakes is thinking that the lexicon as used by liberals must mean the same thing when conservatives use the same word. They don't. They're separate fields effectively, who sometimes use the same word for different things, or different words for the same thing. It's a basic communication skill that many people seem to lack or be openly hostile to: to learn the other side's actual meanings of shared words, and not just hostile caricatures, actually "getting" what is intended or meant.
Trying to get through to conservatives on some point with argument is folly, futile, and hypocritical, if you're not willing to actually sit down and read the basis of conservative philosophy with an open mind. If you do actually read the basis for why they think what they think, rather than a caricature, then you get a much wiser idea of how to frame liberal policies in language and terms that conservatives can agree with.
