Why are they doing it?

When they know public resistance is so strong? When the percentage of people who approve of it has sunk to a new low? When more people than ever are ADAMANTLY against it?

Everyone agrees that the nation is on an unsustainable fiscal path. So Democrats will add a $2.5 trillion entitlement to hurry us further along the path. Tax hikes that could go to reducing the deficit they'll plow into the new entitlement. Medicare cuts that could shore up Medicare's own shaky finances, they'll plow into the entitlement too (if the cuts happen at all). The new entitlement will grow at a projected 8 percent a year, and it's only through gimmickry it's made to look deficit neutral in the first decade. The cost curve of health care will be bent up, and insurance premiums, too, will rise. For all of this, ObamaCare will still leave 24 million people without health insurance.

If nothing else, watching the Democrats sacrifice so much on behalf of this monstrosity is fascinating, appalling -- and dramatic. Common sense suggests that they shouldn't do it. The basic laws of political physics say they can't do it. And yet on they march.
