Well, I haven't spent time there, but I *DO* know my local rep and senator ARE receptive to phone calls, email, and when they're in town (ie, not jeff city) especially drop-in visits. And they actually LISTEN!
OK, so I'm not from KC or St. Loonie, and I can see why people there have given up on their politics.
Believe it doesn't help if you want, but make the calls, send the letters and emails, JUST IN CASE.
One could make an analogy to voting? "Well, my vote doesn't matter, since this is such a democrat ridden area anyway, there's no way the guy (gal) I want will win...blah blah blah" Yet no one here would advocate not voting.
The truth is, sending letters, making calls, stopping in to talk to your representative/senator is like being able to vote on EVERY issue that comes up. When you elect someone, that doesn't mean they're put in office to do as they please until they're up for reelection.
