I think it more likely that the Democrats have committed political suicide again, because the nominee chosen isn't electable in the eyes of the party's rank and file--like the grassroots activists who do the grunt work getting the vote out year after year, and get kicked in the teeth by the party machine year after year.
Seems to me that way too many Democrats are just plain slow learners.
Hint: we got into this fine mess because the Democratic leadership abandoned it's political base within the party, just to get Clinton elected. Clinton represents the old southern conservative Democratic party--the party of Strom Thurmond, and the Democrats who voted for Reagan.
