Is it an oxymoron to say she is incompetent and a leftist?
It’s an oxymoron to say that she’s a leftist and a hypocrite, for sure.
But, unfortunately, the left is quite competent when it comes to harnessing racism, to employing demagoguery, to exploiting Marxist class warfare, etc.
They only become incompetent when it comes to actually governing or running anything other than a political machine.
There’s a joke about a preacher’s sermon manuscript with a note that says, “Argument very weak here; pound on pulpit for emphasis.” That’s pretty much the liberals in a nutshell.
