3. The beer track … without the baggage? Klobuchar’s campaign is likely to emphasize her working-class Midwestern roots, her staff said; you’ll hear stuff about how her grandfather worked as an iron-ore miner, for instance. It will also pitch her to voters on candor, honesty, pragmatism, an ability to “get stuff done,” work ethic and so forth. It’s going to lean pretty heavily into her Midwesternness, in other words.

The idea is to draw a contrast — probably softly at first, and maybe more explicitly if the campaign grows more combative — between Klobuchar and more left-wing candidates from the coasts, particularly Harris, Warren, Sanders and perhaps Booker. In some ways, this will recall the old distinction between “beer-track” (“flyover-state” moderates) and “wine-track” (coastal liberals) Democrats. However, Klobuchar isn’t likely to have the beer track to herself; Ohio Sen. Sherrod Brown could be playing in the same lane, and, more significantly, so could former Vice President Joe Biden. There’s also what you might call a “craft-beer track,” consistenting of candidates who are from the middle of the country but whose appeal might be stronger among college-educated voters, such as O’Rourke and (craft brewery founder!) John Hickenlooper, a former governor of Colorado.
