1) George W. Bush:
It can happen. With a republican majority in the House and Senate AND the president loading up the Supreme court with butt kissers -why not let him run another term.
2) Jerry Springer:

It can happen. Jerry already ran for the House and is the former mayor of
Cincinatti.
3)Bunny Powerpuff

It can happen. Third party candidates rock and just as Ralph Nader proved that he can take away votes from a similarly positioned candidate -Bunny can position herself as "the other mentally challenged" candidate.
