You have got to give republicans credit: they tried their best to kill health care legislation. First, the tried to kill it by an effort to bar "earmarks" in the legislation; earmarks that republicans themselves helped put it the bill. Second, they claimed the legislation was unconstitutional, because in requiring fines for those w/o insurance, the bill violated the 10th Amendment. That idea failed on a party line vote of 60 to 39. Third, the GOP conducted a non-filibuster filibuster and that failed by the necessary 60 votes to 40. Again straight party line. The final vote to pass HR-3590 was 60 to 39.
What does one see in a party that opposed Social Security in the 1930' and still does, opposed Medicare in the 1960's, and now is dead set against a health care plan? The GOP has not met a war it did not want to fund or a social program it did not want to kill.
