Hillary Clinton has achieved her dream. She is finally inevitable. That’s the upshot of Joe Biden’s decision not to run for the Democratic nomination. He was the only candidate of stature who could still oppose her, especially given the prospect that he might have done so with the tacit support of President Obama. “Stature” is a relative term. Biden would be a terrible candidate in any other lineup. He is a famous blowhard who talks first and thinks afterward (if at all), who has a reputation as a foreign policy sage despite being wrong on just about every foreign policy decision of his career, and who is even more associated than Secretary Clinton with the downward spiraling mess of this administration’s foreign policy.
