Stimulus possibly, but health care probably not.

I suppose a big chunk depends on what it is exactly you want or expect a politician to do. If the only things that matter to you are that power is decentralized, freedom increased, & less violence is done at the decree of government officials, then it really does not matter who you vote for. The differences between politicians are largely in what way power be further centralized, freedom decreased, & more violence be done. Those differences are not significant to me so long as one politician is not much more likely than another to launch a nuclear bomb or declare martial law.
