They blame repubs regardless of if they are in power or not.
They do it as their nature because as they are socialists, and innately use the hegelian dialectic, there is always an enemy to struggle against regardless of the issue.
This is why, apart from being liars, they fake hate crimes. They always need an enemy oppressing them to use the hefelian dialectic approach of incrementalist change. Its why where things were 20 years ago they were applauding, now they look at as oppressed and awful. Their system of change demands they abhor the draconian past, hate the oppressive present, and only their socialist “solutions” can make things better in the future.
The flip side of this coin is that Republicans are enablers of the socialists because they don’t have any core principles and they don’t stand for anything. They are appeasers. And so the destruction continues apace.
