That seems to be the conclusion that Andrew Sullivan derives from a recent Gallup poll:

Chris Good looks at the Gallup poll. Large numbers believe healthcare reform will hurt them personally, but support it for the good of the nation. Obama has tried to argue that it will help most people personally. It's the worst sales job he's ever done - because, I suspect, we all know it isn't true.
Err, umm, how do you get that? From what I can tell, 34% think health care will worsen in the US, and 34% believe it will worsen for them...that seems to me like an unusual level of consistency for a poll.
The way I see it, 55% think they will personally benefit, or at least not be adversely effected...not great, but it would seem to make sense given the fact that I'm sure quite a few people haven't personally had a problem with insurance or health care.
Personally, given the fact that we'll still maintain an employer-based health insurance system, I'm not sure my level of care or coverage will change all that much. If the public option is created and isn't watered down too much by insurance-industry backed Congress-critters, my company might be able to move to a cheaper, more stable plan that doesn't increase premiums twice as fast as inflation, causing wage deflation.
Regardless, the idea that Obama or any President can easily sell a major health care reform package "well" is quite ridiculous. People are naturally weary of tinkering with the health care system, largely because their lives depend on it. There is a large, well funded contingency out there whose political and economic livelihood requires a scared, confused, and disgruntled public to stifle a successful health care reform effort.
Its the same reason health care costs have such a high inflation rate...because people don't know enough or aren't confident enough to challenge advice given to them by medical professionals. If a doctor says you need a certain test, expensive as it may be, most people don't have a level of confidence to challenge them over it like they might with a car mechanic or something like that...because if they are wrong, they could die (or at least be unhealthier). So, you throw a bunch of anecdotes from doctors or supposed medical experts out there saying that this plan will hurt them, and people get a little queasy about changing the status quo, even if they aren't big fans of the status quo.
But that doesn't mean it can't be done. I'm sure there was quite a bit of opposition to the Medicare/Medicaid package advanced by LBJ, along with the requisite fear tactics that went along with them (see:
Ronald Reagan). But, we got it passed, and while there are kinks in the system, the elderly generally approve of their level of insurance and care, and there are countless poverty stricken people who owe their lives to the advent of Medicaid.
This proposal is nowhere near as drastic or "socialistic" as Medicare...which is the dreaded Single-payer health care for those over the age of 65. And while Obama's short term favorability ratings might suffer in the short term, a lack of action on this issue will lead to a GOP takeover for sure. In 1993, Dems tried and failed to reform health care, and so they got all the negatives of trying but no positives for succeeding...if we are going to take away a lesson from that fight, take the lesson that we've already started, and so if we fail, we hand the narratives over to the GOP, and our party and country will suffer for years to come.
