A new Quinnipiac poll finds that independents oppose Democrats’ health care legislation by a 58 percent to 30 percent margin — or nearly 2-to-1. Among the broader population, it’s opposed 53 percent to 36 percent.

In another finding, by a 73 percent to 18 percent margin, Americans do not believe that President Obama will keep his promise to cut the deficit. What’s especially shocking, is that less than a third of Democrats — just 32 percent — believe he will keep his promise.

It’s worth keeping in mind that for Democrats to win in conservative states or districts, they must be able to win independents, and at least have a respectable showing among Republicans. This health care bill won’t make it much better.
