Question for Democrats

Why doesn't affirmative action apply to the presidential election?  If the Democrats really believed that affirmative action is a just program that has a positive impact on America, then why aren't they supporting Barack Obama?  The whole point of affirmative action is helping minorities attain jobs and positions they wouldn't otherwise be able to because their race gives them a disadvantage.  Affirmative action, according to Democrats, is a way to overcome America's discrimination of minorities. 

So why doesn't affirmative action apply to the Presidency for the Democrats?  All of the Presidents of the United States have been white males.  Isn't it about time the Democrats step up and nominate Barack Obama outright simply on the basis that history shows minorities are "discriminated" against when it comes to electing them to be President?  Where is affirmative action for that?  Doesn't he deserve the same help that other minorities get when they are applying for a job position?

Why do we need the primary anyway?  Primaries are all about finding who is the most qualified or who would make the best President.  Affirmative action saves minorities who aren't qualified enough for certain positions, and mandates they be hired anyway based on their race. 

That sounds exactly like Barack Obama!  He's completely unqualified to be President, but shouldn't he be handed the Democratic nomination because he part of a minority?  Doesn't he need the help from the government to get the job he wants?
