[EM] language/framing quibble

Good Morning, Kristofer

re: "You may say that parties, wanting to be re-elected, would
      stay in center ..."

I think parties are more inclined to keep one foot in the center while 
stretching as far as they can toward the extreme with the other.  That's 
why we so often hear that the 'neoconservatives' have taken control of 
this party or the 'ultraliberals' have taken control of that party.

The stretch toward extremism to attract the more radical constituencies 
is the dynamic that causes the lurching we experience.
