Politico is reporting that, if Franken resigns, the Minnesota governor will appoint his female lieutenant governor as a placeholder, because she doesn't want to serve in Congress. That would leave the Democrats free to have a primary fight in the next election.

The downside Politico doesn't mention is that appointing a placeholder means the Democrats would be ceding the slight advantage of having an incumbent run, and Democrats would be volunteering to throw dirt at each other in a rehash of Bernie supporters vs. Hillary supporters. Democrats, please don't self-inflict this wound.
