SUSAN PAGE: There’s a clear Democratic front-runner for 2020.

On the theory that it’s never too early to launch the next campaign, the new USA TODAY/Suffolk University Poll has identified an overwhelming front-runner for the Democratic presidential nomination in 2020.

It’s someone entirely new.

Literally. Not an identifiable person. Just “someone entirely new.” When that description was included on a list of possible contenders, 66% of Democrats and independents said they would be “excited” to see such a person jump in the race; just 9% thought he or she shouldn’t run. That’s an overwhelming yes-please-run score of 57 percentage points for, you know, whomever.

That seems wise.
