The Bulwark's Sarah Longwell explains “the Bush line” as the approval floor George W. Bush left office at, 32%, which she says mattered because it helped hollow out the Republican Party and made it easier for Donald Trump to take over and reshape it; in her view, Trump being below that line would signal the MAGA experiment was a failure, burden future Republicans like J.D. Vance and Marco Rubio, and help Democrats in the midterms, especially since she believes Trump doesn’t care much about Republican losses, is surrounded by yes-men, and is focused instead on himself, his legacy, and using his presidency to get rich and go after enemies. Sarah Longwell is publisher of The Bulwark, host of The Focus Group podcast, and author of “How to Eat an Elephant: One Voter at a Time,” out on September 8.
