Personally, I think the biggest and best splash he could make would be Marco Rubio. Jindal seems like a sharp cookie though, who would make a great VP.
Jindal got hammered for that horrid "Republican Response" speech he made two years ago after the State of the Union. he was dull as dishwater and totally lifeless. Typically when a VP choice is a younger man than the Pres, the VP is being set up as the heir apparent. I don't think Jindal could be the man in 8 years. Rubio, however... He is young, energetic, and appeals across the board - whites and Latinos anyway. And Condi - she is a freaking bonafide genius. Her biggest problem is that she is not married - think about it. The constant speculation about her sex life, the lack of a Second "Husband", who she takes as an escort to state dinners - I know that is hardly a reason to knock on her, but it would be the same for a single male VP - if he takes a different woman to every function, he's a hound dog. If he has the same girlfriend for a while, he is living in sin by having sex and not being married - it is a no win proposition for anyone other than a widower - unless he is a long time widower. Then the single man rules apply.
So Condi, while a FAB choice, has liabilities.
