Barry Goldwater, Jr. doesn't appreciate his niece endorsing Obama:

CC does not help the Republican Party nor the cause by minimizing John McCain. McCain may not be everything she wants in a President or hold her exact values, but she should work within the party to promote the ideals Barry Goldwater stood for. Endorsing one of the most liberal Senators in Congress is certainly not the way to help fix any problem she sees; instead it is a betrayal of everything my father advocated government should be. My father would never endorse a candidate or a party that wanted to grow government, raise taxes or in any way step on our freedoms.
