Just wanted to jump in and say this is a very cool thread....
Anyone want to take a stab at "mapping out the Left" for items such as US Senate or Gubernatorial Elections in recent years and historically?
For example, in 2016 the Working Families Party candidate bagged 3.17% in the Oregon US Senate race and the Greens got 2.5% for a combined 5.7%, which would meet proportional representation requirements in many European Countries.... This doesn't even include the 3.1% that voted for Steven Reynolds, who definitely ran to left and was a former Progressive and Green candidate in other elections. The Left captured 8.8% of the US Senate vote in Oregon in 2016 (Including my Vote)....
