last I read it was 39% with all voters and 79% with the GOP

it says something. that the best President, Carter, had such low numbers. Regan lnegioated with Iran to not release hostages until after the election to sway voters and if he won, he'd sell them weapons that was then used to fund more war in Central America (Iran Contra Affair), on his first day tabled a 1000 page policy document by the Heritage Foundation that had 60% implementation within 12 months and directly lead to the fuck up the world is now.

When people ask what led to some. major catastrophe eg Ferdinand's assassination etc, that's the one, all of this entire 50yr+ shit storm flows from the continual decline when voters rejected Carter and chose a celebrity, it's why this will keep getting worse.
