The New York Times: To Pay for Health Care, Obama Looks to Taxes on Affluent
The Washington Post: Obama Proposes $634 Billion Fund For Health Care
You would think that, by scheduling the release of the health care portion of the budget outline for the day before the official release, the administration either wanted to try to bury the tax hike story by allowing Obama to reset it, or it wanted to signal to allies that he was serious about health care reform. My guess is that the administration doesn't care about the tax arguments and is more interested in setting the stage for health care reform.
I think Obama does care about tax arguments, and thats why he emphasized the point in his non-SOTU: anyone who makes less than 250K will not see a single dime of tax increase.
Once he has assuaged 95% of the public, they wont care about these proposed tax increases on the wealthy (which incidentally was a acampaign promise repeated every day last year) to fund health care.
