>>He just isn’t.<<
I see The Donald has taught you how to form a cogent argument.
It’s so obvious, no argument needed for anyone who is paying attention, that Trump is the one who has made all the changes happen over the last few months in presidential politics and beyond.
For one thing (a big one) nobody was taking the power away from the LSM before Trump did it. Nobody else was able to squash political correctness like he has. And most obvious of all reasons Trump is the man for the job is that he is strong/tough and he fights!
But if you feel superior and sleep better by going for the chisel (CRuz) when we need a jackhammer (Trump) then that is your right of course.
