text: Castro is more popular than any other US President because his philosophy is rooted in fighting for the rights of the poor and under-served in society.  More than 80% of the world is made up of hard-working but marginalized people who need a leader to champion their causes, such as fighting for a living wage, universal healthcare, etc.  This is what Castro, Che Guevarra, and Hugo Chavez champion.  They work for the common people -- not for multi-national corporations.  That's why he's more popular.
