So what do we know about who is more likely to win general elections?
(A) They win more swing voters
AND
(B) Because ideologues juice turnout for the other party
Moderates have advantage BOTH in persuasion and mobilization, in other words.
The typical argument for ideologues is that the "fire up" the base. That's true! But they fire up the other side even more. This will be esp. important in 2020 with turnout expected to exceed 60%.
Joe Biden best fits the above theories, though his ties to Washington are concerning among voters who hate elites. Sanders could do better with them, but his ideology is perhaps a bigger punishment.
Thanks to @A_agadjanian for doing good experiments on RR & the primary
& to YouGov for data!
