Napolitano may run. She'd be reminiscent of some of the bad, futile candidates of years gone by, but she'll have her moment, as they did.
The name I've heard is Kirsten Gillibrand. It's sort of the Obama strategy. Find somebody who's gotten elected from a big state who doesn't have much experience or much of a record and hope that they don't make mistakes and can breeze in on a "historic first" campaign. She may well end up as the VP nominee. Blanche Lincoln might also be a possibility or Maria Cantwell.
I don't know much about any of these women. For all I know they are all awful (Democrats, after all), but my point is that we know mid-level or lower-level players on our own side, but don't have much knowledge of their counterparts on the other side (or at least I don't), so we think about Barbara Mikulski (who is still alive and in politics) or Geraldine Ferraro, or Bella Abzug, or Shirley Chisholm (who aren't), because we don't know who's actually out there and available today.
My mistake, Jennifer Granholm is the Current TV lady. She was born in Canada, and (under the old rules) ineligible for the presidency. See, I really don’t know these players.
