Challenges to President Obama's legitimacy, which had begun with fringe conservative authors, talk-radio personalities, TV talking heads, and bloggers, was soon embodied in a mass political movement: the Tea Party, which started to organize just weeks after President Obama's inauguration.

The difference? The Tea Party questioned President Obama's very right to be president.
