Not many people who actually get elected to high office want to be remembered as that crank who got .5% of the vote.
Because it's very rare that somebody with a lofty title like Governor or Senator is going to flush his political career down as an also-ran.
What about former Governors, Senators, or Congressman, such as Ron Paul in 1988, Dick Lamm in 1996, Cynthia McKinney in 2008? Why are cooks who were elected to Congressional districts in past years hard to find?
I guess I'm just really perplexed by the idea of a 3rd Party nominating a pastor (Chuck Baldwin) or an economist as opposed to someone with actual experience.
Why hasn't Jesse Ventura run for anything higher than Governor? He could act as a potential spoiler, plus he hates both parties.
All of those people are regarded as nuts.
(Well, I'm quite fond of Paul personally, but.. yeah.)
