Have The National Dems Learned The Lesson Of Alabama?

No, probably not.  The Dems are not going to do everything to build a vibrant constituency and bring out huge numbers of African Americans and other minorities, working class non-minority voters, aka cracker assholes, women, younguns at every fucking election.  Nope, the Dems will probably continue chugging along as the lame little brother of the GOP and continue to lose most of the races they should be winning--or would be winning if they represented a clear alternative to rock-ribbed conservative neoliberal bullshit.
