The Senate Finance Committee is expected to vote today on its version of healthcare reform legislation. Last month, the Democratic-controlled panel rejected amendments to include a public insurance option. But the insurance industry is still attacking the measure, claiming it doesn’t do enough to force younger, healthy Americans into purchasing insurance. The industry wants harsher mandates so that Americans in poorer health don’t account for the bulk of its new customers. On Monday, the White House and leading Democrats denounced an insurance industry study warning that the Senate Finance measure would lead to increased costs for average families. Some have interpreted the study as a threat to raise costs rather than as an unbiased warning. Democratic Senator John Rockefeller of West Virginia said, “Health insurance companies have been laughing all the way to the bank for generations while people suffer. The industry stands today as the greatest impediment to real healthcare reform.”
