Paul Krugman writes:

What really struck me about the meeting, however, was the inability of Republicans to explain how they propose dealing with the issue that, rightly, is at the emotional center of much health care debate: the plight of Americans who suffer from pre-existing medical conditions. . . .
In reality, House Republicans don’t have anything to offer to Americans with troubled medical histories.

This simply isn’t true. It’s not a matter of opinion. Obama and Rep. Dave Camp (R., Mich.) had a lengthy debate on the Republican alternative of state-based high-risk pools. The video is here. The transcript is here. You can argue, as Obama did, that high-risk pools wouldn’t work, or wouldn’t work to liberals’ satisfaction. But you can’t just assert that Republicans “don’t have anything to offer” and can’t “explain how they propose” to deal with this issue.
