The apparent decision to push Obamacare through reconciliation gives new meaning to the term political suicide. It will almost certainly fail, for one thing. And it will persuade rank and file Democrats in Congress that their leaders have lost their minds, and so will badly divide the Democratic caucus and make for a very difficult year to come for them. An ethic of every man for himself — which is what many House Democrats will have to adopt after this — is the last thing a party in trouble needs in an election year.
