Trump is a dumpster fire, that makes the awfulness of W.'s era just a dumpster in comparison. W. at least understood politics and wasn't trying to break the world. Starting a war on false pretenses and screwing up a lot of things, sure... but Trump is so, so much worse.
And he's only been at it for 2 months. We're screwed if anyone legitimately attacks us right now.
(And of course, there was an entire generation of voters that were at not at all politically aware ages during his term and basically spent their entire lives under Obama, and so have no real concept of what the Republican party can be when its in charge.)
