Unfortunately, what this election does is basically validate Trumpism. The voters could have overwhelmingly rejected Trump and his ideology, sending your party back to the drawing board to hopefully come back with an ideology and political playbook more suited to your beliefs.
Instead, the main takeaway here is going to be "Democrats failed downballot and only narrowly won the presidency, in a year where all the fundamentals were against us. Let's do it again."
I think here are some actual takeaways:
-Trump is radioactive in the suburbs, but the "establishment wing" of the GOP still has appeal. Focusing on economic and "bread and butter" is good, but the culture wars are not.
-The GOP has a huge opportunity to win over black and Latino voters, and have locked down the Cuban vote for good.
-The election was a rejection of Trump rather than an election of Biden. Maybe Biden can be a unifier and help depolarize the country.
-The WWC seems to be a problem for Dems.
