Why on earth would the left rise up? They are in charge. The loony left is running the country, even though it is a small portion of the populace. It has convinced the liberals and the morons in the middle that they are just liberal, not Hugo Chavez in drag. Only the right sees this regime for what it is. I see zero chance of a leftist insurrection, and it would be tiny if it did occur. It would look like a G7 riot, or an OWS rally, a few hundred idiots.
Rank and file leftists are in charge of nothing. They’re oligarch-enabling stooges, too stupid to be prepared for the hell they’ve unleashed or even see that it’s coming.
When the economy implodes and the civil society collapses, leftists will be the first to start burning down the joint.
