There was something off about his obviously intentionally egregious picks, and what you say makes a lot of sense.
In 2016, Trump was an outsider with a few allies. 2016-2020 he bullied anti-Trump republicans like Kinzinger and Cheney, making examples out of them and getting a lot of candidates, governors and House members to kiss the ring. By 2020 on Jan. 6th when it came time to object to certification and stage the coup, the House was deeply infected by MAGA loyalists, but the Senate was mostly immune (with a few exceptions, like perennially spineless Cruz and Hawley).
Now in 2024, the Senate is showing signs of pushback but Trump knows he has momentum from a likely complete House takeover and his election “mandate.” He’s making a statement: “submit.”
My cynical take is that those voters have already tuned out again, and aren’t even paying attention to the consequences of their vote.
When it comes time to personally experience said consequences, they’ll have forgotten their complicity and accept whatever feel-better answer is readily available. No lessons will be learned.
