I know; the Dem Party was organized in 1858. It was the same people that stood hard for slavery during the Continental Congress. I did oversimplify the issue to prevent a lengthy historical monograph. sorry...
***It was only in 1933 that the Democrats wanted to run roughshod over the Constitution because it got in the way of the New Deal***
You are completely overlooking them firing on Fort Sumter in 1861 to start a 'civil war' in order to force slavery on the Constitution.
