Each presidential candidate is traveling to Iowa, and each presidential candidate has a problem or two. Today I’ll be their consultant.
I’ve got a few quibbles with 538’s taxonomy, but it’s a good starting point. Arguably there are five corners to the Democratic primary electorate. 538 draws a distinction between ‘party loyalists’ and ‘the left,’ whereas the better distinction is probably between ‘moderate’ Democrats and ‘progressive’ Democrats, but whatever. It’s a start.
I’ll lay out one key thing each candidate needs to do to get in a position to win the nomination.
