No. I think he could persuade them to put pressure on Dem senators and/or vote them out of office if they continue trying to destroy the country with their open borders madness.
I personally know lifelong straight ‘D’ voters who are going to pull the lever for Trump. Not all democrats are California democrats. You’ve got the penicillin-resistant strain out there.
Before they started invading Colorado, our democrats were to the right of most of the national GOP.
If that was a major issue for those voters, do you think they would be electing the Dems as senators in the first place? There may be some Dems who would support Trump over their Rat senator, but not enough to make a difference.
