Dickerson delves more into the GOP’s divisions:
In most epic battles with a Democratic president, Republicans would swallow their own internal differences and close ranks against their common foe. But that’s not the case in this showdown: Many Republicans are personally invested in their previous argument that the party was headed toward ruin if it shut down the government over Obamacare. Put it this way: If Republicans emerge victorious from this struggle, McCain will have to admit Sen. Ted Cruz was right.
Jonathan Cohn emphasizes the Democrats’ unity:
That [unity] reflects effective leadership, for sure. But it also reflects something else: a shared sense of disdain and outrage over what the Republicans are doing. So add this to the list of ironies about the shutdown: By pushing so hard, Republicans have offended all Democrats, from both houses and both ends of the ideological spectrum. Republicans, in other words, have made their own job even harder.
