Being the Republican nominee is no position of power; see Bob Dole, John McCain and Mitt Romney. He needs something from them, like 35% of active republican voters who say they won’t vote for him.
I agree power was the wrong word to use, strength is a better choice. Trump is in a position of strength because he is, by a large margin; at least currently, the front runner. Your globalist candidate is also willing to throw his carefully crafted persona of being anti-establishment to the curb when it no longer serves his best interest. Let me guess, you believe he is doing it for your best interest. Is that correct?
