Benefits: Dubya could in effect appoint a likely successor, and he's specifically mentioned that he'd like to see Condi in the White house. In fact, a scenario like this is probably the only way that Condi Rice would or could be persuaded and positioned to run in '08. Second, it would help pull the plug on McCain's hopes (however faint) that he could be the nominee. I do not trust that man's judgement or sanity but he might (by early '08) persuade enough Republican voters that he's the "only hope" to beat Clinton II to have a shot in the primaries.
