Ted Kennedy allegedly commented that he wanted to keep his senate seat "in the family..." however, i do not know of any one thinking they are entitled to the Presidency because of bloodline... if someone meets the requirements, they may run and even win... coming from a family of past Presidents should not keep someone from running if they want to... i say go ahead... he is not guaranteed a single vote... let the chips fall where they may...
i am holding out for a true conservative... hope one will step up next time around... Walker perhaps?
However, as you say it is up to us whether or not we allow them that honor.
