So for the republican party, a small outspoken minority is the turn-off or is it their position on certain issues (ie abortion, the economy, educational rights, immigration policies, etc.) that do align with the ideas of those americans that are conservative?

? I think its safe to say that each party has their vocal minority that we wish those on the outside wouldn't use as their rule of measurement (ie Cindy Sheehan and moveon.org come to mind for the more liberal/Dem parties) instead of really researching issues. Not saying that it applies to those that have posted here, but I have heard some of these same points posted before from other people.
But in all seriousness though, we've got to keep in mind that each of us (Af Am) has a varied priority list (if we can call it that) of things that are important to us personally, as well as what we believe to be the best solutions as to what ails most of our communities. That "list" will influence you. For some such as my self, its my faith - for others, it could be their wallet. It just variess, and that's ok.
We can talk about party steretypes and sock puppets until the cows come home and fry chicken. Ailments that disproportionately affect our communities such as broken families, sub-par public educational facilities, poverty, and just a general hopelessness - the thought that your current situation is as good as it will get - have got to be addressed in non-partisan ways.
