In modern history- Bush was easily , as he was hated universally more by the democrats (trump still does well among blue collar Dems) and even hated more by the left (just look at DU threads from 2003-2008 or tyt from 2006-2008) .
Yeah. The antiwar left hated Bush with a vicious paranoia far beyond anything Resistance Twitter has come up with yet. Perhaps that will have changed after a few years, we'll see.
Paranoia implies they weren't actually out to do you harm. 
Sure. But I'm talking about the widespread conspiracy theories on the left during the mid 00s that Bush did 9/11 to start a war in Iraq for the oil and funnel the profits to Haliburton. I also remember the constant rumours from 05-07 that Bush about to bomb Iran etc..
Plus internationally, I'm pretty sure nothing Trump can do will create anything equivalent to the wave of anti-Americanism that the invasion of Iraq unleashed across the globe.
