That is another angle I thought of.
The bushies and GOPe infiltrate the Cruz campaign. They come as supporters, but are actually traitors to Ted’s campaign.
They build up Cruz, so that when the bomb detonates, Cruz falls that much harder and farther (???)
I think more details will be released
That theory could have legs if there was any example of their contributions to Cruz having helped him at any point. So far there is nothing to show for it.
