Again, you are speculating what a criminal who supported a genocide would have done. If someone is ok with murdering children that’s enough not to trust them on any issues.

I will thus vote Democrat, as that is the only rational thing to do.

If you were alive in the 1940 the only rational thing to do would have been to grab a gun and fight the nazi. I’m not suggesting anyone should go to war but there’s no rationality in supporting a system that is rotten to the core. You are free to vote whoever you want but supporting the democrat party and claiming that to vote them is the only rational thing to do is simply not true.
