Are CBO healthcare numbers right?

Contra some of the wingnuts cited in this NYT opinion blog, I don't believe the Congressional Budget Office is politicizing its cost savings estimates on the healthcare legislation. I do believe, though, that it's assuming a willpower on some deferred taxes that may not be real. Also, going beyond the scope of the blog post, I believe the CBO is underestimating the long-term cost of insurance-buying subsidies for poorer people, absent real insurance price controls on the private sector.
