I don’t know if this is ahead of the curve or behind it, but here are a few sites that can help you maintain a reality-based view of the world:

The Commonwealth Fund takes a first look at the presidential candidates’ health care plans so far. The short version: Obama, Clinton, and Edwards would “expand coverage by building on the strengths of the current system–pooling risk in large groups, generating efficiencies through employer-based coverage, and building on the success of public programs such as Medicare, Medicaid, and the State Children’s Health Insurance Program (SCHIP). In contrast, Republican candidates Governor Romney and Mayor Giuliani would rely on tax incentives to induce consumers to purchase individual insurance coverage — now the weakest part of the insurance market.” Read the whole thing here.

Factcheck.org reviews the Democratic candidates’ plans to get out of Iraq. Short version: the front-runners are in no hurry.

Public Agenda‘s a good place to find out if the people are behind you, or running the other way. It finds that “the American public sees climate change as a global problem that requires global cooperation—and U.S. leadership.” Six in ten say global warming should be a top priority for U.S. diplomacy, and nearly two-thirds (65 percent) “say it’s realistic to believe that international cooperation can reduce global warming.”

What other sites in this vein have I missed?
