By Sam Wechsler - Talk Radio News Service The Congressional Tri-Caucus and Congressional Progressive Caucus announced Thursday that they have 53 signatures vowing not to vote for health care reform unless the legislation contains a robust public option. Rep. Lynn Woolsey (D-Calif.), Co-Chair for the Congressional Progressive Caucus, stated that many in Congress who favor a single-payer health care system have compromised to ensure a meaningful public option. Rep. Barbara Lee (D-Calif.), Chair of the Congressional Black Caucus, voiced her support for a public option, arguing that it would guarantee coverage, give people a choice of doctors and hospitals and give private insurers an incentive to lower costs. “Health care should not be a privilege as it has been in the past, it is a basic human right,” said Lee. She also specified that the insurance rate in the public option would be the Medicare rate plus five percent. “We need to lower health care costs. The only way to lower health care costs is by providing competition, and the only way we can provide competition is by having a public option,” said Rep. Nydia Velazquez (D-N.Y.). Rep. Carolyn Cheeks Kilpatrick (D-Mich.) said she doesn't anticipate that any Republicans will vote for a bill with a public option, but added that their votes aren't necessary in order for a bill to pass.
