1. The electoral college system is plainly anti-democratic - its a system that permits election of the loser of the popular vote. That's the very definition of anti-democratic.

2. Google "crosscheck." Its a system set up by Republican operatives that matches last ad first names of registered voters in different states. The states then remove people from the voter rolls (in some cases without even  notifying them). So, "John B. Washington" in North Carolina gets removed because there is a "John C. Washington" in Indiana. The program disproportionately targets black people because of the commonality of some last names (i.e. inherited slave owner names).
Also, look at what, i.e., Wisconsin, Ohio, North Carolina, and various other red states have done regarding, i.e., number and distribution of polling places including number of machines at different polling places); availability of early voting, etc.
