What are 2 long term trends that have characterized the history of suffrage in the u.s.?

1. Originally the right to vote was only permitted to 1) property owners or 2) those that were educated. So the government only wanted voters to be people that had "a piece of the pie" So people, like women or African Americans, were not allowed to vote because they didn't own anything and were uneducated. Also women and blacks had different views and ideas which made the government want to not give them the right o vote because of how it would affect the country; people do not like change. So trends that characterized the history of suffrage where aspects like having money, owning land and having an education.
