“Cruz has never been establishment and fights them. He doesn’t want to be in their club and I do not believe he will give up his principles to play their game.”
Well I guess somebody has to break it to you. Cruz has happily taken on the entire Jeb Bush campaign staff along with his ex criminal brother Neil. And gladly accepted Yeb’s endorsement. So I would not call that fighting the establishment.
Most candidates accept endorsements from wherever they come and they have no control over endorsements- like with David Duke for Trump.
