Matthew Yglesias reminds us of one of the many reasons to be skeptical of the Democratic establishment's embrace of Barack Obama: If the party leaders had had their way, not only would Obama not have been delivering the keynote address at the convention, he wouldn't be the party's candidate for U.S. Senate at all. Plan A was to hand the nomination to Blair Hull, a millionaire who could have self-financed the race. That's a recruiting tactic the party's increasingly relied on since the early 1990s; as we saw last night, it can deprive the country of some of the most dynamic and committed public servants out there in exchange for bland nonentities like Herb Kohl.
