It's just 60 days until early voting starts in 3 states, on Sept 20. (Minnesota, South Dakota, Virginia).

That means the DNC candidates need to be picked in time for paper ballots, voting machines, etc. to be printed or programmed. If that takes 2 weeks or so, then the next 45 days are really crunch time for the Democrats. Decisions and actions will need to be at warp speed!
