Tom Harkin, the Democratic senator from Iowa, says he’s stunned to discover how Democrats and Republicans “may be closer together” than we thought. In saying this, he is echoing something Democrats, including Obama, have been saying all day. Indeed, when Republicans like John McCain and Eric Cantor disagree and say the differences are far more substantive, these are the moments that have triggered the president’s anger. Fascinating. Democrats are seeking to turn around their fortunes on health care by hugging the GOP. It’s one of the more peculiar political strategies in memory, but when you’re at 25 percent, it might be worth a shot. A long shot, but a shot. A very long shot.
