Nope the Whigs were the predecessors of the Republican Party (mostly) and their opponents were the Democrat Party founded by Jackson.
It was anti-slavery for the most part and that "for the most part" was what brought it down. The party split on whether slavery should be allowed to expand in the US or not.
Thank you for the correction. The point is -- and I do have a point -- is that the Jacksonian Democrats were in favor of slavery.
And I think you know where I am going with this... At what point did the Democrats become the party of choice for the minorities? And the party of Lincoln (the Republicans) become the suppressor?
