Actually, the Democratic party has a long history of embracing white nationalism and a short memory. If you do not recall of the Democratic party of the past, then you must be young.
Meanwhile, the Democratic party has often and repeatedly embraced the endorsement of the Nation of Islam, a clearly anti-Semitic organization.
The interesting thing is that while this piece highlights that Repubicans including Romney repeatedly denounce members that show any support for white nationalism, the Democrats have repeatedly at multiple times refused to denouce members or organizations that have made anti Semitic statements.
