For Missouri Democrats, tomorrow is judgment day.

After leading the Show Me State for most of its existence, voters will decide if the last two Democratic statewide officials remain in their posts. If U.S. Sen. Claire McCaskill and state Auditor Nicole Galloway prevail, it could provide a jolt for a party seeking to rebound after the disaster of 2016.

But if GOP Attorney General Josh Hawley is able to topple McCaskill, and Saundra McDowell is elected auditor, it could be the surest evidence that once-purple Missouri is now deep red.

Those two races aren’t the only things on the electoral radar. Voters will also decide on several major ballot initiatives — including three on legalizing medical marijuana. And across the river in Illinois, Republicans are on the defensive after Gov. Bruce Rauner’s tumultuous term.
