Here's an actual compliment I want to give the Oregon  electoral system: it's way more efficient than California's., while each have certain innovations.  I found this out when I became interested in a particular race for a California  State  Assembly  seat.  Two big differences from here: everyone runs in the same primary regardless of party (except presidential); and the state operates  both a same day election and a huge mail-in operation.  
    The result of the first is that in many districts, the top two-- who go on to the General-- are  of the same party, usually Democrat.   Often  the favorite gets maybe  2/3 of the vote and a couple others scramble for the leftovers at 20%  or so each.
The INCREDIBLE RESULTS:  With all this, it's total chaos.  Hundreds of thousands of votes still uncounted from that recent election!  Many  races, mostly for second, still undecided.  Few fingernails left.
