Being creative (artistic types) requires the use of BOTH HALVES of the brain. After a few years of practice, full use of the brain can be applied to almost any facet of society, ie, politics. This results in more well-rounded individuals, capable of complex thoughts and emotions. Republicans are good at rage and hate and revenge and spite and betrayal and cheating and lying. Democrats are good at empathy, respect, wisdom, fair-play, openness, decency, law & order, and helping the sick and poor.
