Howard Dean’s Healthcare website is tracking support for public health care within the Senate and the Congress. This link goes to the screening page. The lists produced show that 1 Democratic Senator is a confessed opponent of public health care, (Landrieu from Louisiana) and that 27 members of the body are “don’t knows”.
Among the “don’t knows” are those who oppose public health insurance as anti-competitive. The chart included below groups Dean’s “Don’t Know Democrats” by the states they represent with the market concentration ratio of health insurance companies in their states.
