Sounds like you have been sucking sour grapes after the events of last night. Trump is not 'establishment'. Ted Cruz is/was establishment all the way. A 'Bush' by any other name is 'Cruz'.
When you are done with your time of mourning, know that there s room on the Trump-Train for you. We need unity to defeat Hillary in November! FRegards!
I will look at it objectively, weighing Trumps character flaws and some bad policy against some of his character charms and good policy.
