2005 NJ Gubernatorial Election Outcomes

Possible outcomes:

1. Republican candidate wins election, Corzine goes back to his Senate seat and runs for re-election in 2006, effectively unupposed. What is the likelihood that the Republican candidate has enough of a coat-tail to get some control in the state legislature?
2. Corzine wins election. Whom does he appoint to his now-vacant Senate seat?
3. Republican leading significantly in the September polls due to some unforseen scandal, and Dems (using the Toricelli rule) replace Corzine on the ticket. Whom do they pick?

Discuss amongst yourselves.
