This story is very poorly backed up. It's sheer speculation.
Even if Condi wants to run, and even if she'd be a stronger candidate as vice president than as (recently resigned) secretary of state -- both huge "ifs" -- I can't believe that Bush wants to lose Cheney, or that Cheney would quit if Bush still wants him, absent an extremely serious health issue. Things this dramatic rarely happen in politics, and Cheney is not an especially dramatic guy.
You would think it is written in stone...Saturday fluff.
