My Politico column pushes back against the over-reading of Hillary’s debate performance:

Las Vegas was a reminder that it is awfully hard to lose a nomination if no one truly plausible, let alone formidable, is running against you. The structure of the Democratic race from the beginning has been been about propping up Hillary Clinton, and it still is. The party is putting on a master class in how to nominate someone under FBI investigation, and is willfully in denial about her vulnerabilities.
Yes, Hillary had a good night. She was polished, knowledgeable, shrewd and hard-hitting – clearly, not someone to be trifled with. But the debate was a false indicator of her strength.
