Cuz like… the self destructive Republican behavior no longer seems self destructive to me at all. (Regular destructive, maybe.) It looks… effective, given the Republicans' specific goals.
My entire adult life I've been, as a leftist, told, and sometimes argued to others, that there's a particular way of gaining power & influence as a political faction. That way has never worked. What the evidence says is effective seems to be the opposite of how the center keeps telling the left to behave.
