Obamba's arrogance.

The narcissist’s anger and intolerance is projected on his followers who also become angry and intolerant of criticism of their leader. The followers get their narcissistic supply by elevating the status of their leader. The greater he looks, the better they feel. They see their glory is his glory. Conversely, when the narcissist is criticized, his followers become offended. They take those criticisms personally and their instinct of self defense is triggered. They will become vigilantes and will silence their critics through intimidation, bullying, mocking, threats and violence (like calling those who disagree with Obama, racists). Exactly what he is doing now.
