I know that democrats wanted new states to be able to choose to have slavery, but a constitutional amendment that they didn't support removed that from their platform. I know that when California became a state that both parties had the same ideals for a while, trying to win votes in the new territory. I know that as businesses no longer needed large investment into infrastructure by government, republicans switched to the platform of smaller government in an effort to reduce their tax burden and regulations on their activities. Yeah yeah yeah, we know about the switch.
But you gotta admit, you were actually the one that brought it up!
