Not going to happen. Elections are the fig leaf used by the powers that be to give them a cover of ‘legitimacy’. Many people will see the elimination of that fig leaf as the signal that the time to start shooting the bastards had officially come.
There is a world of difference between Postponing elections (indefinitely) and canceling them outright.
I would tend to agree that the outright canceling of elections would be a major tipping point.
But postponing them for little while .. until the powers that be consolidate their power might not be the same thing . Their story could be that were just doing this until the emergency is over and keep it on doing it until its advantageous for them to have them again.
(Even a Socialist Workers party lead by Hitler had elections massively skewed they were but they had them none the less)
