i foresee not more than 3 people running for presidency!
all based on THE NOMINATION PROCEDURE.
unlike other times the office of the Registrar of political parties will be vetting the so called signatures of the nominators. 2000 signatures from at least 24 counties? ALL VERIFIED to be
1- voters
2- members of your political party (or in the case of independents, members of no political party)

The one move that will throw the whole thing into chaos is a web interface where the public can check if they have been 'illegally' registered by these political parties.
