Never mind the fact it was a republican president that freed the slaves.
Jim Hoft at Gateway Pundit reminds us of a little history regarding the democrats and their support of slavery:
When the Civil War ended, and after Republican President Abraham Lincoln liberated the slaves in the south, Democrats initiated Jim Crow laws to punish blacks. Democrats discriminated against blacks. In fact, the KKK, was founded as the the terrorist wing of the Democrat Party.
The Ku Klux Klan assassinated many Republicans including Republican Representative James M. Hinds (December 5, 1833—October 22, 1868) of Little Rock. Hinds represented Arkansas in the United States Congress from June 24, 1868 through October 22, 1868.
But, since when do facts matter with liberal Democrats?
