Palpatine kinda DID end the voting system (analogue to parliamentary democracy):
"The Imperial Senate will no longer be of any concern to us. I've just received word that the Emperor has dissolved the council permanently. The last remnants of the Old Republic have been swept away."
-Grand Moff Tarkin
