While fraud is definitely a problem, in the case of Medicare it may be that some doctors are attempting recoup the underpayments that Medicare pays on every claim.

What The Obama/Pelosi gang want to do is CHANGE CROOKS..They don't want competition in what they think is their private hunting ground. (Healthcare).

Expand the waste and fraud prevalent throughout the government.
