To start, I'm not very knowledgeable on the candidates and I'm not American, so I might be a bit off in the process. But I want to look at this from a strategic viewpoint. Hopefully you find this viewpoint informative. I've been mulling over whether or not the gop deserves to win the Senate. This is of course assuming that votes will be counted fairly, which I doubt. This is coming from a viewpoint of "I don't want the Dems to control the Senate, but clearly the GOP are a bunch of snakes".

Firstly, the GOP clearly doesn't deserve any votes. The aren't, for the most part, backing Trump. But that doesn't necessarily mean that you dump them right away. Pause and Plan. The GOP has betrayed GEOTUS. Now is time to plan the revenge not to react emotionally. How to do this? Well firstly, if they lose in a landslide, they'll know they need to adapt. As slimy politicians they will promise whatever they need to for the next election. Alternatively you can lull them into a false sense of security by voting to try and let the Republicans control the Senate then wait until there is a more promising alternative, some kind of America First Party, then drop them. Sending a message by not voting for them at a time when they'll be able to adapt is the wrong thing to do from a strategic viewpoint.
