Democrats are challenging Republicans to renounce any insurance options provided by the federal government because the GOP unanimously opposes the healthcare reform law, which they refer to as "Obamacare." During the opening days of the 112th Congress, Rep. Joe Crowley (D-N.Y.) offered a measure that would have required members of Congress to disclose whether they benefited from government-sponsored health care. The GOP blocked Crowley's proposal 240 to 191. Members of Congress do not receive free government insurance but purchase private health insurance through the Federal Employees Health Benefit Program, the nation's largest employer-sponsored health plan with an estimated 2.15 million workers. The federal employees program provides a smorgasbord of almost 300 private plans, "the widest selection of health plans in the country," according to the Office of Personnel Management.
