Nate Silver has an excellent post wherein he breaks down 25 major issues being pushed by Obama and the Democrats, and sizes them up against public opinion polling.
The bottom line?
Of these 25 issues, Obama's position appears to be on the right side of public opinion on 14: the bank tax, repealing the Bush tax cuts for the wealthy, campaign finance, the credit card bill, D.C. voting rights, fair pay, financial regulation, gays in the military, hate crimes, the jobs bill, mortgage relief, PAYGO, SCHIP, and Sotomayor. It would appear to be on the wrong side of public opinion on five issues: the GM/Chrysler bailout, Guantanamo Bay, health care, the extension of the TARP program, and terrorist trials. On the other six issues, the polling is probably too ambiguous to render a clear verdict.
Republicans, on the other hand, have been overwhelmingly opposed to almost all of these measures with the exception of Ben Bernanke and Afghanistan troops, both of which poll ambiguously, and the credit card bill, which polled well.
Obviously, this analysis is superficial in certain ways. All issues are by no means created equal, and health care in particular, which is unpopular, has weighed heavily upon the public's perception of the Democrats. In addition, there is probably another layer of 'meta-argument' that goes beyond specific issues, and at which the GOP has tended to excel.
Nevertheless, it runs in contrast to the objective evidence when one asserts, as Hanson does, that "On every issue … the Obama position polls 5-15 points below 50 percent." Rather, the votes taken by the Republican Congress have far more often been out of step with those of the median voter.
Silver's caveats are well-advised, but the larger point here is that Obama and the Democrats are, for the most part, doing what the people want. One wonders then why they have a hard time actually getting things done.
