I briefly alluded to this, but health care costs should take precedence over the uninsured. Maggie Mahar seems to agree:

Rather than focusing on the uninsured ““or the fact that insurance companies sometimes deny care to the insured”” we should focus on those who are insured, and remind them that as the economy slides (while the nation’s health care bill continues to rise), their employers are going to find it harder to continue paying such a hefty chunk of their health care bill.

However, cutting costs means denial of services, which is much less politically appetizing than covering the uninsured. The wrong issue is being emphasized on the political trail.
