The worst thing about the whole "we used to love him until he did x" misses the issue that leads to these situations in the first place; it would more accurately be "we used to love him until we realized he lied to us."

That's what American political campaigns are and have, as long as I've been listening to them, always been: A long series of lies and overstatements told in order to gain office. That people continue to believe them and lavish praise onto these liars encourages them and guarantees we'll continue to see this happen long into the future.
