Because Democrats use that excuse to take the attention off of themselves.<quoted text>
How do you know it's not a rightwing conspiracy?
Remember Bill Clinton letting his wife go on national television to make a fool of herself telling the nation her husband was the victim of a massive rightwing conspiracy?
And then Bill Clinton publicly admitting the very next day he really was lying?
No one takes the rightwing conspiracy excuse seriously anymore.
Obama promised the nation answers and accountability. He has offered no answers and no one has been held accountable.
In fact, his initial outrage has become empty rhetoric trying to take the attention off of himself.
There's your rightwing conspiracy.
