Honestly, we didn't really expect to hear back from her. But we felt more confident we'd hear something from Senator Barbara Boxer, who has apparently been more interested recently in taking national stands. At the very least we thought we'd hear back from Congresswoman Barbara Lee. But we didn't.
If we didn't have full-time jobs over here, we'd call the offices directly instead of emailing them. But emailing them should be just as effective, if they offer the opportunity to do so. If they're not willing to be responsive via email, then they shouldn't offer the option. End of story.
Contact your representatives and demand to know where they stand on issues that are important to you. You're paying their salary, for crap's sake -- if your boss wanted an answer from you, you'd give it, wouldn't you?
