LOL! Pretty much.
DFL stand for Democratic-Farmer-Labor.
Until 1946, there was a Democratic Party AND a Farmer-Labor party in Minnesota. The Democrats were more establishment-oriented but the Farmer-Labor wing was pure Far Left material.
Both parties realized that they were allowing GOP dominance in this state and decided to merge. Hubert Humphrey and Eugene McCarthy were instrumental in getting this done.
Within 4 years, they had to lead an ugly and protracted purge of Communists who had taken refuge in the Farmer-Labor party prior to the merger. Humphrey, etc. realized that the Communists would affect their parties' electability. Humphrey was also very anti-Communist as well.
