Trump already started his shift.

Trump never claimed to be the intractable conservative who would never ever work with the establishment or cartel as Cruz labeled them.
Trump will stay true to his basic platform but those voting for him understand he wrote The Art of the Deal. Trump’s not a lying hypocrite like Cruz.
I wonder if Cruz understands that the longer he stays in this race, the more he cozies up to GOP, the more supporters he loses and lessens his chance for any other position.
