If the Democratic congressional candidate underperforms the Democratic presidential candidate, it definitely sends a signal.
Obviously, it only "sends a signal" if progressives say what they're gonna do.
But it has a double whammy: Dems get a 2 vote difference when you switch.
You have to look at the bigger picture, not the short term issue.
If progressives want to be taken seriously, and if Americans want AIPAC out of politics, then there have to be consequences.
If Latimer and Bell hold on to the seat, corporate and AIPAC Democrats only learn that they can take progressives for granted.
If they lose their seat, they learn that they need progressive support to win.
Yeah, two years of a republican rep will suck. But it's only two years.
