If you mean by “not ride his train” as vote for him, I’ve said here a lot that I wouldn’t vote for him. By the same token, I won’t trash him or his supporters.
All of this will burn out when the media and Democrats realize he’s touched a hot button with a lot of people in this country who have so far been largely silent, and they will shut up. At that point, Trump loses his edge.
I “mean”.... as so many are doing (for many varied reasons) - carry him on their shoulders, elevate him.
When he gets nowhere, all his dirty laundry and past positions will be fitted to hang on the Republican field - fair or not, because that’s what the MSM does.
