Jan Brewer's Racist Finger

Was Jan Brewer's finger motivated by racial animus when it wagged in the president's face? The race warriors are swarming.

...the reality is, we live in a country, we live in a world where there is, you know, bias that we have that is subconscious...

While many in the media have speculated that Brewer might have caused the dust-up for political gain, I've not heard anyone suggest the more likely scenario that the president - who plays politics with every issue, no matter how serious - made the scene to stoke his base.
