Lincoln only freed the slaves in the south.
Where do you get your history from? Most of the northern states were "free states". Remember, slaves from the south would escape to the north via the Underground Railroad. Also. the Emancipation Proclamation was part of the 13th amendment. It covered the whole nation. The Republican Party was formed for one purpose only. Abolish Slavery. It was their platform. I would be happy to send you a copy of the Republican Parties 1860 platform.
