Im simply not worried about NH in a 50/50 election.
FL, AZ, NV, and NM could all be safely Bush's if he nominates Estrada to the SCOTUS, should there be an opening.
If things get rough (continued flat job creation), Bush could drop Cheney and put someone from Ohio on the ticket.
kerry's voting record will also help in WV and Ohio
There simply isn't any prominent Ohio Republican political figure out there. Taft isn't popular, and Voinivich and DeWine would be rejected by the GOP base for their centrism.
