Washington, D.C., is a different place in August. Hotter — today, just shy of 100 again — and much quieter as the cacophony of sound bites coming from Capitol Hill fades to a few chirps. When Congress is on recess, it can seem like the whole town has shut down. Not so. The money machine is always open.
