Was the outcome of that election better for the long-term health of the country? Was foiling a DNC plot to avoid a primary worth losing the election? I don't have those answers. I can only say that I am displeased with the current state of affairs.
Was the outcome of the 2020 election better for the long term health of the country considering how things are currently? It seems pretty clear that regardless of which of these two worthless parties wins, things always get worse in the end as they only work for themselves and their donors.
By continuing to offer support to either party, you're just continuing the status quo. Democrats don't need to do jack shit to earn anyone's vote when they're confident you have no other choice except "the boogeyman," and Republicans play the exact same game. People who think we need to "vote blue no matter who" would gladly elect a Democratic version of Trump because they're playing a team sport and it doesnt matter how bad of a leader or how big of a piece of shit they elect just so long as their team 'wins' the contest. The result of this is visible in every aspect of our crumbling nation. None of them are willing to do the job of actually repairing the damage done when they can just virtue signal over hot button issues and win your vote off that alone.
Continually "sucking it up" and electing a piece of shit because the other guy is a bigger piece of shit is precisely why we're in the mess that we're in because you're ensuring that a piece of shit is always the one winning.
