I am answering for me, not EveningStar.
I am not voting for Trump, or for any Dim or GOPe candidate or nominee, but I am voting for the down ticket races that comply with those restrictions, and any State and local issues and question on the ballot.
In other words, your assumption in general is flawed.
I'm voting for Trump. Only Trump. If I have to write him in.
I'm also voting for my US Rep, who is an early endorser. I'm not sure I'll vote for anyone else.
I've spent some time today researching other political parties in the event that I need to leave the Republican Party. We've had a good run, over 35 years. But my salvation doesn't depend on being a loyal Republican.
