In general, the US system of determining a president is less than ideal. In many cases, we are left with choices that are between two people that we would rather not be president. In those cases, for me at least, my vote is based more on policy than person. For many evangelicals there is only one issue that moves the needle for them and that's abortion. Personally, (although I understand that moral position) I don't think there will be a change in abortion policy with a conservative in office. However, I am more in line with the platform of the Republican party than I am with the Demcratic party, so what's a guy to do?
Also, this is clearly a political post.
