DCCC playing favorites

The Democratic Congressional Campaign Committee is now interfering in Democratic primary races:

The Democratic Congressional Campaign Committee (DCCC) has in recent weeks injected itself into almost all of the major primaries remaining despite pledging previously to abstain. . . .
Only six races with competitive Democratic primaries are currently listed as “toss-up” or “lean Democratic” by the Cook Political Report. The DCCC has now picked a side in all six of them.

This is extraordinarily un-democratic, and if grassroots Democrats aren't offended, they should be. It's very bad for the national party to pick candidates in competitive primaries. One of the ways that the Bush-led Republican Party destroyed grassroots enthusiasm in the GOP was by playing favorites in the primaries.

Even in the case of incumbents facing primary challengers, the national party leadership should stay out of these local intraparty races, since to do otherwise sends a signal to local activists that they don't really control their own party.
