because the elites run all parties that call themselves "democratic" all over the world - at least in europe and in usa.  as elites run and finance these, they don't need smart people. they need corruption and idiots who will be monkeys and do the elite's bidding.  that's why when you look at democrats they are all looking like mentally ill / insane. because the elites who run them selected them to be mentally insane.
