The problem is that people think they can outwit the fundamentals.
You need to vote EVERYTIME - even if it's pointless - because you need to complete the tit-for-tat exchange. If you do not complete the exchange, then you have lost all of your leverage. This is negotiation 101.
Even if you don't vote Democrat, you need to vote for someone - you cannot abstain, this is always the worst option. Voter suppression is obviously a different story, but if you're choosing not to vote, you are not suppressed.
I think this is a "walk and chew gum" situation. We can do both.
For the sake of transparency, I am not a Dem. But I do find it beyond criminal that Dems (even if it's grassroots) has not whipped up an organization to both threaten a third-party AND primary Dems.
This also gives Dems diversification in strategy. The opposition will now have to counter two potential threats while protecting home-court. It really makes too much sense.
But unfortunately Dems are allergic to winning. This is not even to shit on you (you are probably not a Dem whip), but just an observation I've had. It's always 0 or 100, and highly telegraphed strategy. No precision, no timing, no urgency - just losers.
