I have just read the article again.  With reference to Schumer's idiotic comment, that we need the jungle primary in order to avoid "polarization," note the following:  According to political science professor Boris Shor, who studies polarization, California has the nation's most polarized legislature, and Washington has the fifth most polarized legislature, based on data released a few months ago.  I do not know where Alaska ranks now, but we certainly do not need any more polarization.
