I wonder whether the insiders are trying to use Trump to knock out Cruz and then focus on knocking out Trump.
Trump will face a different kind of enemy once all of his primary opponents are gone. It'll be the nameless faceless media, and you know they've got tons of material.
I mean, if such a big ado could be made over Cruz taking out a margin loan with his own assets as collateral, and making a paperwork error, I imagine that in a few months they'll make a complete hash of Trump.
And he will not be able to respond to a monolithic media with the same affect as he has to individual opponents.
Of course he'll have a much easier time if Hillary is the nominee, but I do not think she'll make it much farther.
