It is rigged. On both sides of the aisle.
If you’re part of the ruling class that must be alarming, as the spectre of pitchforks and hot lead surely cannot be far behind.
Once people truly realize that they have no input into the game, it's over. The Zombie Apocalypse won't be far behind.
Every 4 years you start hearing conspiracy-minded folk talking about the current pResident cancelling elections so as to stay in office. It comes from both sides. When Bush was in power, it was driven my leftists, when Clinton, and now Barak, it's being pushed by some on the 'right'. Regardless of what side is making the claim, it's a fantasy, because the ruling class know that once their fig-leaf elections are gone, their rather tenuous claims of legitimacy evaporate in a puff of logic.
This is the last thing they want, because open season starts, with many Unintended Consequences.
Note: I love a good conspiracy theory probably more than the next guy, but this one isn't in the cards until the establishment thinks it's time to go all in.
