If others vote as I do, according to what they value, most of them will probably vote either Republican all the way, or democrat all the way.
Except it's not going to be about values, it's going to be about hate -- or more specifically, disgust. Each side is banking on the other's supporters being thoroughly disgusted with their respective Congresscritters.
The Right expects the Democratic Congressmen to face backlash for the impeachment -- or for the very least, for failing at it. The Left expects the Republican Senators to be held accountable for what they did to themselves to defend Their Great Leader -- do they represent the people, the Party, or Donald?
Personally, I think we're going to see a lot more of the latter.
Look at the 2018 midterms: Donald was out there stumping for his loyal supporting Congressmen, still riding high on a good economy, in a midterm where the GOP had the House (which they decisively lost), and where 26 of the 35 Senate seats up for election were the Dems to lose... but in the end, the GOP only gained 2 seats.
Not only that, but the Dems gained 7 gubernatorial seats. Not only
that, but some of the GOP victories were close races in districts so traditionally red they should have been no-brainers.
Were those elections based on values, or on disgust?
The Nevertrumpers are often dismissively called "haters," and I'm not one to argue it... but haters vote. If that's what 2018 looked like, what do you think will happen in 2020?
What you call a "hatred of the alternative" can happen for House and Senate candidates as well. The 2 parties are very polarized and each side is fully entrenched far apart from the other, and the dem or Rep candidates are pretty much in line with whatever the upcoming presidential nominees are going to be.
Ah, but it's not the candidates that are disgusted, it's the voters. What do you do when you're so disgusted with your own candidate's behavior that you can barely stand holding your nose and voting for him, but at the same time, you're not about to change parties?
Answer: You choose "none of the above," and skip the whole thing.
I'm betting that more Republicans will do that in November than Democrats... as I said, Donald is protected; his minions are not.
