I got about a half dozen busy signals before I got through to Feinstein. So she is answering her phone (at least at the San Diego office).
I don't hold out any hope for Boxer, but Feinstein is smart enough to know that this bill is a train wreck.
Just keep hitting "redial" until you get through.
Point is they don't have to care what anybody thinks. They know they'll never have a better chance than this for decades.
