WHILE DEM INCUMBENTS SHIFT LEFT TO GUARD AGAINST PRIMARY CHALLENGES, THE GOP NEEDS TO COME UP WITH SOME ACCEPTABLE CENTRISTS CHALLENGERS: Ed Markey pairs with Alexandria Ocasio-Cortez on Green New Deal.

UPDATE: I find some of the responses here disturbing. Look, sure, you want to elect people who agree with you 100%. But it’s hard to get a majority that way. The Dems took the House by running centrist (or centrist-appearing) candidates who could win in close districts. You’re not going to win a seat Ed Markey holds with a Ted Cruz, or Tim Scott. But somebody who caucuses with you and votes with you most of the time is better than someone who caucuses with the other side and votes with them all of the time. And just by running someone you make the Dems defend what would otherwise be safe seats, leaving them fewer resources to go after others. This is Politics 101 and it works.
