Ah, so the idea is that candidates for the position are not yet locked in, therefore comparison between party candidates is not valid. I can get behind that.
However in the current environment I don’t see many other paths forward. I think the best alternative I’ve seen was an article floating al franken. My guess is the original commenters worry is that without viable alternatives, it will likely become a Biden vs trump election, and by then we’ve provided ourselves with enough negativity against Biden to encourage a trump victory. I’d like to see more positive qualities of alternatives be brought up, instead of negatives about the current most likely nominee.
