I think the DNC and their consultants did that. I saw an interview with their consultants after the election, and they were all "We have no idea what went wrong", etc. etc. They all think that Trump is some wild anomaly, not that their strategy sucks. Anybody could've told you that people were tired of the status quo, so a status quo candidate would have trouble winning.

Actually I'm starting to feel convinced the Democrats saw "The Producers" as inspiration.

"You can make more money with a floploss than a hitwin!"

As long as they keep losing elections, they can keep making money disappear (via laundering it). They sop up all the donations and laugh all the way to the bank, burning LITERAL BILLIONS OF DOLLARS on their cousin-in-law's "strategy consulting firm" and tons of completely ineffectual "vote blue" spam, and pay themselves six-figure "speaking fees".

The solution isn't to just stop voting, though. Voting is merely the least inconvenient, easiest to access tool in the toolbox and the people who left it unused are morons no matter how much ELSE they are doing ABOVE AND BEYOND that. Voting is the bare minimum; you have to do that AND local party organizing, civics, community engagement, nominating candidates for local races.

But if you don't vote TOO, it's like you neglected to wipe your ass. The stink follows you and embarrasses everyone with you.

Completely irrelevant because

1. This is what "forcing" the democrats to make a change looks like, all it will ever do is shift the overton window to the right and make things even worse.
2. What really lost the democrats the election was years of gerrymandering, voter suppression and making it just difficult as fuck to vote in Dem areas.
