Garry Kasparov really and truly doesn't like Kirsan Ilyumzhinov's "successes" as FIDE President, and although his attempt to help Anatoly Karpov win the presidency in 2010 failed, he wants to have another go at it in 2014, even if it means he himself will be the opposition candidate.
Kasparov has done a lot for chess over the years with his fantastic play, and his charisma and energy brought major corporations like Intel, IBM and Microsoft into the game for a time. On the other hand, he did more damage to the world championship title than a year's worth of Anand-Gelfand matches while helping to alienate those same corporations as well. (Most famously in the case of IBM, when in the second Deep Blue match he all but accused the IBM team of cheating.) So if it's a race between Ilyumzhinov and Kasparov in 2014, the best candidate may be "none of the above".
