Clinton's victory speech tonight is probably the best I've seen her give. Good on the policy, laced with actual themes, and relentlessly driving home the importance of Ohio. The problem is, at the end of the day, she'll still have to trash the likely nominee, overturn the will of the pledged delegates, and force through a change in the DNC rules to win. Her speech is good, but what it signifies, for the party, is quite dangerous.
