In the election of my local representative there are only two realistic contenders - both from the 2 main parties. No one else has the resources to send out all the junk mail and recruit all the college kids to harass people. And the funny thing is - just like probably most of the congress people - our representative isn't really all that bad. She's just not really good. She's just a nice old lady that's a vanilla career democrat. The chances she'll be voted out are effectively zero. So I just don't vote for people any more (i leave it blank). However, I still go to the polls to do the ballot initiatives
