What Cruz and Beck really mean, of course, is that the majority of the people chose a candidate that they don't like and therefore they act as though the choice between Trump and Hillary was somehow forced upon them. If anything, the establishment did everything in its power to attempt to foil Trump's bid, but the people overpowered the establishment. It is on the Democrat side that they might have an argument, as we now know that the system on that side was clearly rigged in favor of Hillary.
The bottom line is that Cruz is consumed with his own ambition and Beck allowed his irrational Trump hatred to drive away most of his viewers/listeners (including me), and the resulting implosion of his empire is driving him over the cliff.
