Please, the tea party is just a bunch of American racists being funded by billionaire special interest groups (ex.: Koch Brothers), to create anarchy for the first Black president and the democrats.
It is in the interest of big business, big banks, the oil companies, etc., that this administration fail and democrats become unseated because they need a republican controlled congress in order to make sure they continue to be able to do business unchecked and unaccountable.
Special interest groups like the Koch brothers are financing the so-called tea party; these special interest groups are merely using the tea party members to make it appear as if this administration's policies are in direct opposition to what the voters want, when in reality, this administration, it's policies and vision for this country are in direct opposition to what these special interest groups want; accountability, check and balances in place, over-site of financial institutions, labor laws, and business practices.
The tea party i.e., America's racists being backed financially and having some of their neaderthal characters and points-of-views cloaked with fake rationalizations of being apposed to this administrations policies are a fraud. If all the issues that the tea party claims to be opposed to were their true agenda, then, the tea party would have been started shortly after George Bush was elected.
As far as Black people being members of the tea party, that isn't any different than Black people being members of the republican party, even after the only reason for republicans' rise to power has been at the expense of African Americans by their politics of demonizing Black people in America (from the welfare queen, to Willie Horton, etc.). They are no different than the Black man who marches each year in the Confederate Soldiers parade, especially since the republican party crawled in bed with the most racist southern politicians, (recently, beginning with Reagan). So, now the republican party is dominated by racist southern politicians and only get elected to political office by racists Americans and via campaign contributions of special interest groups, that in actuality are the same people that have shipped American jobs overseas, are always against increasing the minimum wage, are against national healthcare, are against employee rights and workplace fairness and intend to do business in other countries at American taxpayers' expense.
