After checking on federal law and determining that my job does not prohibit me from donating, I sent her a campaign contribution and added myself to her mailing list. In response to a e-newsletter she sent to her distribution list, I also dropped her a note saying that although I couldn't vote for her (because I live in Maryland), I did give some money and wished her luck. Rather to my surprise, she send me a thank you note from her iPhone -- folks that high up the "food chain" typically don't have time for things like that, so I was pleased to her back from her.
