Your post brings up a very important message -- because I would NEVER vote for myself for President.
The point being, a candidate's position on the issues is only PART of the package when picking a candidate, and in some cases may not even be the BIGGEST thing to worry about.
You need someone who can DO the job. If they can't do the job, who cares if they are right on the issues. Then you need a person who can apply their beliefs correctly -- it doesn't do much good to be "right" on their thinking, if they have no ability to translate that into policies that work.
