No, he should obviously drop him and replace him with Romney.
Actually, that is an absolutely brilliant suggestion. Thank you for thinking of it. It would provide bipartisanship to the administration in these trying economic times. At times of crisis, it is beneficial to have an administration that reaches across party lines.
In addition, with Mitt Romney as Vice President, it would mean that the most qualified individual in the nation would be stepping into the Presidency should that become necessary.
better yet, Romney/Biden '12
Even better, Romney/Romney. Ann Romney would make a stellar Vice President.
