I recently had an anti-Trumper do something similar to me. He found some pro-Cruz comments I'd made in 2013 when Cruz was battling with the Gang of 8, and re-posted them in order to 'shame' me.
I sort of scratched my head and wondered out loud why he was bothering, as I wasn't going to retract a word I'd said. At the time, it looked for all the world to me that Cruz was doing the Lord's work in the Senate, and I fully supported him in that.
It was only recently that I discovered the worrying details contained in his amendment to the amnesty bill that was being voted on at the time.
Had I understood what was under the hood of that amendment at the time, I would have been as turned off then, as I am now. In my view, it's just too slick by half, to offer an amendment that gives any sort of aid and comfort to the invaders - while calling it a 'poison pill'.
Anywho....the knives are out, and some folks are so desperate to support their favored candidate, they'll draw blood on their own brethren to support him.
Yes, welcome to that club of used to be BIG Cruz supporters.
Little by little and then, rather rapidly, my tasted for him turned to bile. Oh well.....
