To clarify, I'm not talking people who want to support Trump, but are afraid to.
I'm talking people who are on his side and would back him in a minute, but either he's convinced them to pretend not to, or who have decided of their own volition to do so to get into all the dirty little secret meetings, etc. to undermine the cabals from within.
Think reps/senators who bash him in public but quietly feed him info on the side, or who wait for the right moment to undo the Leftists' damage.
Dunno why I'm asking, the idea just popped into my head.
Yeah, someone else pointed out "infiltrator" might be a better word for what I mean, lol.
