I normally vote Democrat on the national ticket, and most of my family does too, but I always keep an open mind. I really vote for the person who I feel best represents my beliefs and will run the country in the direction I believe it should go. Usually I'm somewhat on the fence, and so I hem and haw for a while, watch some of the debates, read the paper, and then vote for a Democrat in the end. However, this year I'm really on the fence more than usual - I'll have to see the debates etc. and really listen hard.
On the local scene, I'm all over the place - I don't vote by party at all and I tend to have a 50/50 split between the parties - that really depends on what I read in the paper about their stances on various matters...
