Of course Blatter won't go in advance of tomorrow's 'election' of FIFA President; he's already paid or promised millions for votes to buy the election - he's not going to waste his investment. Blatter has a long history of buying FIFA 'elections' since his very first bent office-taking and now owns many of the micro-votes - i.e. votes from the tiny nations or pseudo-nations. His personal record of corruption is second to none.
The man has more front than Blair. Unless he's banged up, I expect him to go right down to the wire tomorrow.
