Another day, another busy signal!

Again today I have tried and tried to reach Senator Feinstein's office.
I called each of her offices in DC, SFO, Fresno, LA and San Diego.
All busy! I called the capitol switchboard and the operator told me that her phone lines have been busied for hours. My only option is to keep trying to call!

Are her lines busied by furious Americans or pro illegal supporters?
Feinstein remarked that she had only gotten 8,000 calls. Could that be because it is impossible to get through to her? Could it be that it suits her purposes to have it appear that people are apathetic and not bothering to call? How many calls would she have to report if the calls were able to get through?

Strangely Senator Boxer is available almost every time at every office.
Why is this?

Are we being busied out by Feinstein?
