End is near for much of Democratic field

Twenty Democratic presidential candidates will debate Tuesday and Wednesday night. It will be the last time voters will see some of them on a debate stage.

The Democratic National Committee’s rules for inclusion in early debates, the first from NBC in late June in Miami and the second from CNN this week in Detroit, were quite generous. If Sen. Michael Bennet, currently polling at 0.0% in the RealClearPolitics average of national polls, got in both, then it’s safe to say the rules were not terribly restrictive.
