Yes I agree which is why we primaried the fuck out of them and got a ton of candidates that aren't as easily distracted or deranged. That still doesn't change the fact that I would pick one of them over a Republican any day of the week and worry about it next time they are primaried. And yes, if I thought a third party had any notable momentum over them whatsoever I would vote for them instead but you cannot let the R win no matter what at the end of the day.
And edit, just so we're clear, the Republicans are actively building the camps as we speak and I hope it goes without saying that any alternative to that is preferrable.
Second edit: people downvoting me can you even prove any sort of superior rationale here? You have the burden of proof here to tell me what your plan to oppose this is even realistically capable of.
