Kate Shellnut, a blogger on religious issues, for the Houston Chronicle gives us a capsule of who makes up the Tea Party:
According to research conducted by Public Religion Research Institute members of the Tea Party movement tend to be non-Hispanic whites who support Sarah Palin and rely on Fox News Channel for news on politics and current events.
According to the survey, 80% of members of the Tea Party movement identify themselves as Christians and 57% consider themselves to be conservative Christians. Members tend far more toward social conservatism than to libertarianism and three-quarters identify or support the Republican party. About 11% of the adult population identifies as a member of the Tea Party movement.
The survey cast aside conventional beliefs that the Tea Party movement was as large as the "old" Christian right, that the Tea Party was an independent political movement and that its members were champions of personal freedom and liberty.
