Cruz is conservative but also VERY establishment. His wife is a wall street "insider" and Cruz is obliviously a passenger on the Cheap Labor Express. He wants to increase H-1b visas 500%. that should tell you every thing.
So you can shout "populist" at Trump supporters and I can retort establishment at Cruz supporters.
Working for a Wall Street firm does not necessarily suggest that the employee of the Wall Street firm would put Wall Street special interests ahead of America's interests. That is unnecessarily insulting to Mr. Cruz.
There is no reason for those who support Trump & Cruz to get into foolish exchanges with those who are presently supporting one or the other. As one of the former, I simply make a point consistent with my first reply, immediately above.
