The 2018 midterms are a story of two chambers. Democrats are in the best position they’ve been in since 2010 to win a majority of seats in the House of Representatives. The Senate map, on the other hand, is so tilted toward the GOP that most political analysts have all but dismissed Democrats’ chances of winning the chamber before 2020. It has even been suggested that Republicans could gain enough Senate seats (eight) in 2018 to amass a filibuster-proof majority (60 seats).
This is normally the part of the article where I push back on the conventional wisdom and argue something like, actually, the 2018 Senate map isn’t that bad for Democrats. But no, it’s pretty bad: Democrats are a long shot to take back the Senate. CONT.
