Who is electable?

Why don't Americans elect scientists

I found this to be a very interesting article on who is considered electable and what makes an American politician. I found that combining the middle, often sound byte (technical spelling intentional) adverse, positions that scientists take on issues with the drive to the extreme of the current parties in the primaries held for most elections makes a scientist unelectable in most current political elections. A house election where there is a bi-annual need to prove one's loyalty to the party, is the opposite of what most sciencetists want to do.
