The Republicans’ noisy breakdown has been echoed eerily, albeit less loudly, on the Democratic side, where, after the early primaries, one of the two remaining contestants for the nomination was not, in any meaningful sense, a Democrat. Senator Bernie Sanders was an independent who switched to nominal Democratic affiliation on the day he filed for the New Hampshire primary, only three months before that election. He surged into second place by winning independents while losing Democrats. If it had been up to Democrats to choose their party’s nominee, Sanders’s bid would have collapsed after Super Tuesday. In their various ways, Trump, Cruz, and Sanders are demonstrating a new principle: The political parties no longer have either intelligible boundaries or enforceable norms, and, as a result, renegade political behavior pays.
Political disintegration plagues Congress, too. House Republicans barely managed to elect a speaker last year. Congress did agree in the fall on a budget framework intended to keep the government open through the election—a signal accomplishment, by today’s low standards—but by April, hard-line conservatives had revoked the deal, thereby humiliating the new speaker and potentially causing another shutdown crisis this fall. As of this writing, it’s not clear whether the hard-liners will push to the brink, but the bigger point is this: If they do, there is not much that party leaders can do about it.
