Did I say earthquake?

Here's another sign of the tectonic shift.

The NRCC dropped $7.8 million yesterday into 30 House districts.

But here's the thing. It's not just the size of the expenditure. Of the 30 districts in question, 27 are currently held by the GOP.

They're playing defense. But as the GOP playbook says, the best defense is a strong offense, so 98% of the $7.8 million is going to attacking the Democratic opponents.
