Letzrock,
you missed something there, when I say party of slavery, I mean that they used the slaver issue to further their cause after the war. following that, they have been the party to come up with the most enslaving programs than anyone else, starting with Wilson who wanted to enslave the people by getting rid of the Constitution, to FDR who gave us the New Deal or actually the NRA which was so restrictive that it was hard to believe we actually had it and to Kennedy/Johnson who gave us the civil rights act, the war on poverty and immigration reform.
Tie the past of the party with today's version of it and you get a more specific party who wants to erode the Constitution to the point it is worthless. We already have the head of our homeland defensive organization, DHS coming out and saying what the democrats have been saying all along - the people who invade our country are not criminals.
With the twisted thinking of the party, with the rewriting of the congressional rules to shut down opposition, and the more and more legislation from congress that is harmful to our country, no one can say that the party is not the party of slavery.
