HEALTH CARE: President Obama's much-anticipated speech to a Joint Session of Congress starts at 8pm ET, but until then there will be two questions being asked: "What are the 'specifics' he's going to lay out in terms of health care?" and "What progress will the Senate make on their version of health reform today?"
With regards to the first question, Mr. Obama is walking a tightrope, especially regarding his support of the so-called "public option" or government-run health care. If he shows only tepid backing of it, the large number of liberal Democrats who support it will be sure to revolt moving forward. House Speaker Nancy Pelosi insisted yesterday that a public option will be in any legislation that comes out of the House.
However, if Mr. Obama comes out solidly in support of it then he risks backlash from the significant number of moderate and conservative Democrats in the House and Senate, who could derail his attempt at reform. There are at least a couple of dozen House Democrats who have said they'd vote against any bill that includes a public option and House leaders such as Majority Leader Steny Hoyer and Majority Whip Jim Clyburn have publicly backed off the call for a mandatory public option.
The
Wall Street Journal's Jonathan Weisman and Janet Adamy report that the president will "endorse" the public option in his remarks tonight.
"President Barack Obama, in a high-stakes speech Wednesday to Congress and the nation, will press for a government-run insurance option in a proposed overhaul of the U.S. health-care system that has divided lawmakers and voters for months.
"White House officials say the president will detail what he wants in the health-care overhaul, as well as say he is open to better ideas on a government plan if lawmakers have them.
"Democratic plans call for requiring most Americans to carry health insurance. Failure to comply could cost families as much as $3,800 a year, according to a new Senate proposal.
"The president is likely to say that a government-run insurance plan, known as the 'public option,' will not provide a level of subsidies that give it an unfair advantage over private insurers, according to aides familiar with the speech preparations."
