This is an open seat vacated by one-term Republican gubernatorial
failure Matt Blunt. Jay Nixon's strength is not just good for Missouri
(obviously), but has potential national implications.

The more I think about it, the best presidential picks are
"chemistry" picks, those that put two nominees together who like each
other and work well with each other (like Gore or Cheney). Veep
nominees that attempt to compensate for a weakness only serve to
highlight that weakness (like Lieberman or Bentsen). And very few veep
nominees can deliver geography (like Bentsen or Edwards). But when the
two candidates like each other and work well together in purpose and
message, it's pretty powerful.

And on that front, while she's not my favorite veep pick (which is
still Richardson), I think that Sen. Claire McCaskill would qualify
brilliantly. She may be perhaps Obama's most loyal and hard-working
surrogate, and she'd nicely complement Obama's message of change. And
if you see them together, they are a great team.

Normally, I'd flat out oppose it, given that she'd cost us a Senate seat. But the Missouri Governor is sworn in before
the President of the United States, meaning that if McCaskill was our
vice presidential nominee, her replacement would be chosen by Gov. Jay
Nixon.
