As the Senate prepares to vote on the latest version of the health care reform bill, Roland Burris is being closely watched. The Senator holds a key vote for Democrats, who are looking for 60-votes for their plan. Some lawmakers do not favor a government-sponsored plan, but Burris is in favor of the controversial public option. He's seen as one of the Senate's most forceful defenders of it and vows to vote against any plan without one. Democratic leaders are said to be searching for a solution that would appease Burris and moderates in the party who are concerned about the cost of a government-sponsored plan.
