No-one can be as bad as tRump in any direction but this is only because of same Bush tax cut.
Really, you can't compare tRump and Bernie.
The young disappointed Sanders voters are going to vote green, the older voters who don't like Bernie, they can vote green too and to those for whom the choice is Satan or Satan, well, welcome to the Tribulation (2020-2026 convergence).
I certainly think Trump is a horrible president. I am also overwhelmed with how much the left feels they need to twist things and push things. It's frustrating, because those of us who like to analyze and consider the evidence end up having trouble sifting through the mess to find out exactly how bad he really is.
Remember that I'm talking about moderates like myself. We are willing to vote either way as long as the candidate is the best of the choices. However, we are not going green party. If my vote is wasted anyway, I'm voting libertarian.
You do raise a good question, though. If the moderates (usually the deciding vote in elections) are being ignored by both left and right, how damaging is it to chase off the greens or very progressive voters? Most of them are like me, they would be happy to vote left if it was closer to their views. Again, a moderate dem would wipe the map.
As for Trump compared to Bernie, you are right. Bernie is honest, consistent and a good man. Trump doesn't strike me as any of those things. However, Bernie has some policies that could be as detrimental as anything Trump puts forward. I think he would put a better face on the country and we would be less entangled in scandal, but I also think he's bad for the country.
I just feel like the left, who I generally prefer, is failing bad in their approach to Trump. I think people like myself are just wanting the left to say he's a cancer, but we are too far in with too little to do about him and move on. Fighting him is useless. He's already lost all the votes he will lose and the better battle is to show how much better things
could be when we replace him. Continuing to spend all this time and energy smearing him isn't helping and it's starting to hurt bad.
