One of the many reasons I think New England is great is that its elections are conducted — and its results are reported — at the city/town level, not the county level. That lets psephologists like me study them in greater detail, and one election I’m particularly interested in is the just-concluded 2018 U.S. Senate race in Massachusetts.
For Sen. Elizabeth Warren, the race was little more than a tune-up for the 2020 presidential campaign she is now gearing up for; she breezed to re-election by 24 points (although it was arguably an underwhelming performance given the state’s blue hue). But we can look at who voted for Warren in 2018 for clues as to who might vote for her in 2020 — both in the primary and, if she gets there, in the general election. CONT.
