Bite my tongue and know that in a year or so they're going to be looking down the barrel of approval ratings that'd make Dubya say goddamn.
The honeymoon period's gonna wear off real quick once people actually have to drink down that our president, our nation's face to the world, is going to be popularly regarded as a trainwreck at speaking, diplomacy, empathy, graciousness, professionalism, you name it. It's one thing to display those things when you're running against a candidate your party has been furiously stroking a hate boner against for 20-odd years, it's quite another when that context is gone and he's just out there with his ass flapping in the wind.
The Republicans played themselves hard with a Trump presidency. If Hillary won, they could have had another four years of unchecked "everything's terrible" smokescreen-laying no matter how well she was actually performing, and cashed in big on it in 2018 and 2020 with some candidates that weren't so polarizing and objectively vile as Trump. Now that they've embraced the presidency of, jeez, just the worst candidate possible and an all-around terrible human being, they'll be lucky if their party's not seen as radioactive for years to come.
