First, I have little doubt that Musgrove would be more progressive than Wicker on a range of issues. As such, his election would almost undoubtedly make the entire chamber more progressive (even if it would add another conservative to the Democratic caucus). But more importantly, Musgrove would vote with the Democrats on key procedural votes much more often than Wicker. While Musgrove might not always vote with the party on the underlying measure, he would be a significantly more reliable vote on procedural votes — cloture votes to help override a Republican filibuster — than Wicker. This, in and of itself, is reason to support Musgrove.
