Win or lose, there is one sure Election Day bet for the Democrats: Wednesday brings the first day of the 2016 Democratic presidential primary race that's expected to attract Secretary of State Hillary Clinton, Vice President Joe Biden and New York Governor Andrew Cuomo.

Early version had former Michigan Gov. Jennifer Granholm listed, but she's Canadian born, thus not allowed to run and we don't want to get into another birther issue.
