What Mr. Obama should be doing

This morning on NPR, Cokie Roberts, dependable voice of Conventional Wisdom, said that for President Obama, "it's all about the independents;" according to her, that was the reason that the President dug in his heels over the social-issue riders that the most radical Rebuplicans wanted to stick on the budget deal.  

She may well be right, but that's not a good thing.  In fact, it exposes a central fallacy of Mr. Obama's approach:  He should not be trying to appeal to independents.  He ought to be working at changing their minds so that they become Democrats.
