If you don't vote...then you are leaving the "heavy lifting" to the rest of us...
I don't understand how you can possibly question whether you not voting is the same as voting for a dem..
This country is esentially a 48% - 48% nation..with only about 4% of people that can be influenced...so your ONE VOTE does matter, IMHO>
If it means anything, a lot of democrats I talk to ( the normal ones:') aren't all that happy with some of their leaders either.
