It was an anti-Obama rally. Racism was there.

The Boston Tea Party has been misunderstood by historians. Thom Hartmann clarified what it was. The East India Tea Company had a monopoly and was forcing local businesses out.
The stock holders included King George.

The rebellion was because of the rights of the local businesses to survive.

"Taxation without representation" was not the real cause. It was corporate monopoly.

The use of the Tea Party to rebel against Obama doesn't quite fit the analogy. Tax cuts
do nothing to keep corporations from bilking the public. If anything, it protects their coffers.
