Condi has exposure, but as I posted above, she's staff. She needs serious elective-office experience, preferably as a governor -- or shall we make that Governator? She needs to be out in California next week, getting groomed by Ahnuld and other top Pubbies to be their next governor.
J.C. Watts is top people and a political threat to the Democrats, to break up (finally!) Deal with the Devil that the black community's leadership made with the urban Left back in the 1930's. But he has only been a Congressman, he needs heavying up. Not yet ready.
J.C. Watts should consider running for governor of Oklahoma if he has higher ambitions. Rudy Giuliani should consider taking on Hillary Clinton for the U.S. Senate seat from New York. (Giuliani, unlike Watts, does not have to prove his executive ability.)
Dan Quayle made a big political mistake in not returning to Indiana and running for governor after Bush 41 and he were defeated in 1992. The last non-current office holder to successfully run for President was Richard Nixon and that was in 1968.
