An interesting bit of speculation over at TPM Café:

Some top Democrats say that if Hillary Clinton wins the Presidency, which would vacate her Senate seat, they'd like to see New York Governor Eliot Spitzer appoint another Clinton to take her place -- Bill Clinton. The Examiner reports that under this scenario, New York law would dictate that Bill stay in his wife's Senate seat until 2010, at which point a special election would be held for the seat.

Um. Horse. Cart. Proper order.

In the - to me unlikely and eminently undesirable, but let's entertain the thought - event that the dynastic succession to the White House works out and America continues down the path of monarchy, it would make sense to stay in the same rut and hand the Senate seat to the husband of the departing incumbent. Thing is, Governor Spitzer - who would be making the choice - would probably come under intense pressure to nominate a black or Latino replacement (as TPM notes), or more likely a woman. That would probably lead to H. Carl McCall or David Paterson, or maybe - one can dream - Liz Krueger.

Now that would be interesting.
