How did the answer to the question, "Who should have the right to vote in a democracy?" change from colonial times to the present?

well most of the time the answer to that question in colonial times was only rich white men should vote. Of course as time went on we realized hey maybe other people should get to decide what happens in our country, (I say decided what it actually was was a wide spread protest and debate) this lead to the 15th amendment in 1870 that gave African men the right to vote and the 19th amendment in 1920 that gave white woman the right to vote.
