Tea Party/Republican Betrayal?

Don't the Tea Partiers know that the Republicans will turn their backs on them as soon as they're elected, just like how the Dem's turn their backs on the LGBT and pacifists? All politicians care about is getting into office and lining their pockets, not so much what the people want. They may do something simple, like p a birther law, to keep you on their side, but they won't repeal healthcare or scale back spending.
