When you’re the “inevitable” front-runner and polls from 3 or 4 months ago have you blowing your opponents out of the water and then you start losing races by large margins always with some kind of excuse (my supporters work) or lies (I was outspent) what’s the word that you’re called? I mean when you’re not the inevitable front-runner any more, but are expected to fight for votes?
It’s not ‘underdog’. You were never the underdog, no matter how much your campaign tries to spin it.
Candidate. That’s what it is.
