President George Bush (R-TX) / Vice President Dick Cheney (R-WY) ✓
Senatoe Joe Lieberman (D-CT) / Fmr. Congressman Tim Roemer (D-IN)
Lieberman loses bigger than Kerry, but I doubt it's a landslide because the nation was in a right-wing mood at the time and Lieberman was as good of a choice for that as Kerry was. The trouble is that he doesn't excite the Democrats' base and probably turns off WWC. Picking an architect of the Department of Homeland Security as his running mate doesn't help, even if he opposed it later. At least Kerry balanced the ticket with the more progressive Edwards.
