You are known by the company you keep and those with whom you associate. While I believe that it is important who is the President, it is equally if not more important whom that President surrounds him/herself with.
Frankly, The Rev. Wright, Fr. Pfleger, Bill Ayres and his bride Bernadette, are not exactly the people I would choose to have associated with the President. These people clearly hate America. There is nothing wrong with dissent, mind you, but hatred for the institutions of the country and our society is not dissent.
BHO's association with these folks demonstrates an astounding lack of good judgement. Judgement, in my view, is the key characteristic that one must have to be President. Good judgement - whether in considering temperament for the Courts, Cabinet Offices, or Foreign policy - makes all the difference in the success or failure of an administration.
That is why BHO's association/acquaintance with these persons is important and how it will effect his ability to execute the office of President.
