Lots to wade through here and it is clear that the President's lofty early numbers are beginning to become more realistic. He remains very popular personally, but his policies and actions are beginning to be more closely scrutinized by the public. The decline in his numbers is starkest among independents, the large muddle in the middle that determines Presidential elections.
Republicans must continue to target centrist/right of center leaning independents who went Obama's way in 2008. On health care, the path to victory and legislative power is in presenting these voters with a reasonable program for reforming health care that does not threaten the care they already have. Insuring more of the uninsured would be nice, but not necessary.
