I agree with you. It's amazing but it also shows that the establishment has a glass jaw and they know it.
Yes, they do, but it took an outsider like Trump to land the blow that knocked them on their keister. Few, if any, politicians are suitably situated to take on a subject as important as illegal immigration so truthfully and as point-blank, as Trump did.
What I love about his positioning is the fact that the political establishment can't lay a glove on him. There's no string to pull, no coattail to yank, no funding to threaten, no promotion to deny - just nothing. They don't own him, and he's not for sale.
