Why do the Tea Party people support candidates that do the bidding of corporations and who support Wall Street?
The TEA Party is an acronym for the Taxed Enough Already Party.
Under the umbrella of this very loosely organized group are all kinds of different people with all kinds of different agendas although they are mostly against the intrusion of government into the lives of citizens.
As I understand this group of groups, there is no national organization that represents all of the supporters. There is no particular person that speaks for all of the groups that claim affinity with the ideas and there is no particular defined Party, in the sense of the Dems or the Reps, that organizes this group into controlled voting blocks.
That said, what "bidding" and "support" are you specifically referring to?
