Rich Lowry at NRO highlights this piece from Real Clear Politics. I liked this line toward the end.
This bill may encourage a few Democratic policy wonks to run to the polls, but this trickle will be nothing compared to the flood of angry Republicans and Independents. And this is all analysis conducted before election ads begin to run telling voters about how the Democrats will jail them if they don't buy health insurance. To which the Democrats will respond “no, you see, it's only a big fine.”
