Furthermore, Cruz is totally betraying his early supporters. He promised them he would break the Washington cartel. But, it seems, he has reneged on this promise and is now a member in good standing of the Washington cartel.
Yes. He should have disavowed the support of Bush, Mitt et al. They are the oligarchy.
Cruz position on many issues is closer to Trumps position than to the “Washington cabal” as he named it.
But Cruz lusts...
Senator Cruz’s promise was that “if elected president”, he would break the Washington cartel. He has to be elected first. The Washington insiders opposed him with all they had until the field winnowed down to the point there was no viable establishment candidate. They then tried to get him to come to them and make nice but he refused. The ones who support him now are doing so because they have no other alternative. In essence, they have accepted the fact that they have lost but their calculation is that they will lose less with him than with a democrat. If they thought Mr. Trump could defeat a democrat, they would probably support him as he would be much easier to co-opt after election.
I am sure Mr. Trump understands this situation. In his large real estate ventures he has almost certainly taken on partners he was not in total agreement with but he needed them to make the venture work. Many business have owners with a minority interest but while it is better to be a sole owner, it is often better to be a majority owner than to let the project die.
