Without sixty votes in the Senate, Majority Leader Harry Reid (D-NV) would not be able to invoke cloture, or cut off debate. Anything short of sixty would allow a filibuster and doom Obama’s health care plan. The present 60-vote majority is artificial, the result of undemocratic means. Consider how three of these votes came to be:
Roland Burris- Appointed by Illinois Governor Rod Blagojevich just prior to his removal, Democratic leaders including Harry Reid pledged that he would never be seated. Barack Obama, along with other Democratic officials in Illinois, called for a special election to fill the seat. When it became apparent that a Republican could win, Obama and the others backed off from their request. Obama, Reid and the rest of the Democratic establishment eventually acquiesced to Burris’ appointment. The media was strangely uncritical of the sleaziest political deal of the decade.
If former Illinois Democratic Governor Rod Blagojevich thought his problems were behind him, the worst lies ahead. Late in January the state legislature voted to impeach and expel him from office. But it's not just his job but also his freedom that may be lost, thanks to pending testimony from his former chief of staff, John Harris.
