It's so tempting to shrug
"Business as usual", you might say.
But really, it isn't. This kind of perpetual grandstanding is a relatively new phenomenon. As recently as the Clinton administration, legislators were capable of working together to actually legislate about things. (Usually the wrong things, but that's extra.)
I blame 24 hour news, and Newt Gingrich. In that order. (24 hour news created the climate in which every viewer thinks they're some kind of fucking expert on everything they watch, and Gingrich weaponised that mass-Dunning-Kruger-effect to create the attitude that bipartisanship is basically treason. But if he hadn't done it, someone else would have. It's mostly crap journalism that got us here. Unfortunately, the WWW actively penalises every other kind.)
