Is this the best we can do?

Honest people can disagree about who should get the democratic nomination, but consider this.  If Sen. Clinton wins the nomination and goes on to become President, our country will have had a Bush or a Clinton running things since 1988.  Is this the best we can do?  300 million Americans and we can only vote for two families?  One more question.  I have been struggling to understand something that Sen. Clinton has repeatedly asserted throughout her campaign, what experience is she citing as her chief qualifier for President?  Unless I have missed something, she has never been an executive, has only a few years in the Senate more than Sen. Obama, and didn't have a security clearance when she was in the White House.  I'm sure she has great qualities and everyone says that she is incredibly smart, but what experience does she have that justifies her campaign claims?  Why and how is she so qualified?  And finally, if experience is so important for positive change and experience is what is needed in this political environment, why isn't Sen. Clinton supporting a Bill Richardson Presidency?  Didn't he have the most "Presidential" experience then all of the candidates?
