Pretty topical since progressives are watching to see if any dems vote to confirm SC nominee Neil Gorsuch.
During his presidential campaign, Sen. Bernie Sanders never quite decided whether his "political revolution" could coexist with the Democratic Party or needed to overthrow it. Now, Sanders is one of the most popular political figures in the country and the activists he galvanized have gone on to start new groups, join old ones, or run electoral campaigns.
While they've yet to prove they are capable of being any kind of a force to be reckoned with, a handful of groups that grew out of the Sanders movement have already begun issuing primary threats against Democratic incumbents. One called #WeWillReplaceYou has warned specific members of congress it may challenge them. But it promises to use discretion in targeting only those Democrats it feels have strayed from the party. It's a step farther than previous liberal efforts, which have fielded challenges to establishment favorite Democrats in open races but generally not against elected party members.
Democratic officials say they're not too worried about primary challenges in next year's midterm elections — the Democratic Congressional Campaign Committee declined to comment — but the Tea Party showed in 2009 and 2010 that grassroots opposition movements can sometimes turn on their own party. But for Justice Democrats' founder, liberal media personality Cenk Uygur, what seems to matter most is inflicting damage on the Democratic Party. The group's website features an image of a sledgehammer smashing the "D" logo of the Democratic National Committee and declares "it's time to rebuild the Democratic Party from scratch."
