I'm skeptical about the assumption that this long, drawn-out primary process is necessarily a bad thing for the eventual Democratic candidate. But it's certainly a long slog if you're covering it. In any case, if you're a certified primary process junkie, be warned. Tonight is the last primary or caucus until Pennsylvania on April 22nd. Tonight is Mississippi's big moment. And as usual we'll be bringing you live election results starting at 8 PM Eastern when polls close in the Magnolia state.
