Why would a Republican vote to defund Obamacare, but object to a strategy that seeks to use the threat or reality of a government shutdown to defund Obamacare? One possibility, raised by Andy McCarthy, is that Republicans don’t really oppose Obamacare at all–they oppose the strategy because it might work. “The Republican establishment resists President Obama and his agenda only when it knows that resistance is futile, token and sure to be inconsequential,” he writes. Another possibility is implied by Andy’s discussion of the potential benefits and costs of the strategy: that they oppose it because they don’t see those the same way as Andy does. But it does not seem to be a possibility that Andy takes seriously, since by the end of the post he is again saying that Republicans who oppose the strategy are not “for real” and don’t really want to undo Obamacare. Maybe taking a different view from Andy on the likely consequences of following the strategy is itself proof that a Republican is not “for real,” is a Washington game-player, etc. I’m not sure. I am sure that Andy really does not like Senator Corker.
