Advantages: Many celebrities are independently wealthy making them less likely to be beholden to wealthy contributors and interest groups. High name recognition and personal charisma can capture voter interest (both pro and con) and increase turnout. Has to spend less time fund-raising and can spend more time focusing on the issues.
Disadvantage: Lack of political acumen and awareness makes celebrity politicians easy prey to be manipulated by handlers and staff. Just because someone is popular doesn't make them informed or a leader. Speaks in generalities instead of specifics as not to offend certain gropuis so they end up with no definite position on the issues.
There was a song called "Cult of Personality" and I think what we're seeing in California is it in full effect. Minnesota caught a lot of flak when Jesse Ventura ran and won the governor's office. That was nothing compared to the madness going on in Cali right now where it seems everyone and their little brother is running.
I mean GARY COLEMAN????
