Cruz winning by manipulating, lying to and probably bribing delegates. Trump winning the people. Trump winning the AMERICA FIRST voters.
This is the key narrative that needs to get around
In winning the support of the voters, Trump owes the voters - he is bound to represent the best interests of the People. When Cruz "plays by the GOPe written rules" and buys off delegates - and those behind them - he owes his soul to them, not the voters. In other words, the Cruz worm shedding its skin and turning himself into a GOPe snake.
