That’s the wrong thinking. The vast majority of Republican voters are Pro-Trump. We are the GOP now. Third Party isn’t an option, that’s why Trump ran as a Republican in the first place, to get the foot in the door to takeover the party. We cannot throw that away. It’s our GOP now!
With a little luck, I’ll be dead by the next Presidential election, so I won’t have to worry about who I’m going to vote for, and I’ll make sure my kids send a verified copy of my death certificate to the Board of Elections to remove me from the rolls. I did that with my sister when she died in 2011.
