I just heard some commentators on CNN note that the preliminary exit polls suggest that the Democratic primary electorate is more moderate than it was in 2016. But they didn’t point to one of the obvious possible explanations for this: Because the Democratic race is the only competitive contest today, some unaffiliated voters who might have voted in the GOP race in 2016 are now voting in the Democratic primary this year. That, of course, could have affected turnout and the ideological makeup of the electorate.
