The 19th amendment says that citizen can't be stopped from voting, and that it doesn't matter if they are gay, or lesbians. It helps expand democracy because these people can have their voice heard, and that's why democracy is basically.
There were some policies where in the balance of slave and
Free State was kept. A good example of
this was the Missouri Compromise.
However, When the Kansas Nebraska Act came it threatened that balance
since states can now decide among themselves. Eventually it took the American
Civil War to end slavery in the United States.
I have no idea, but the closest thing I could find was a quote saying, "snapping the shutter"
