Matthew Dowd told ABC News that every time "you feel a losing campaign, these three things happen":
"The first thing happens is, don't believe -- the public polls are wrong. That's the first sign of a campaign that's about to lose. The second thing, we're going to change the nature of the electorate, and you're not seeing it reflected in the polls. And the third thing is, the only poll that counts is Election Day. When you hear those things, you know you're about to lose."
