“Broadly speaking, there are two kinds of voter suppression laws. Many provisions currently being pushed by Republican state lawmakers make it harder to cast a ballot in a certain way — such as by mailing in the ballot or placing it in a drop box. Or they place unnecessary procedural obstacles in the way of voters. These provisions often serve no purpose other than to make it more difficult to vote, but they also are not insurmountable obstacles.
Other provisions are more virulent. They might disqualify voters for no valid reason. Or allow partisan officials to refuse to certify an election, even if there are no legitimate questions about who won. Or make it so difficult for some voters, who are likely to vote for the party that is out of power, to cast their ballot that it’s nigh impossible for the incumbent party to lose.”
“the most common kind of law that seeks to make the results of an election impervious to the will of the voters: gerrymandering. The Census Bureau expects to provide states with the data they need to draw new congressional and state legislative districts this fall. Once that data is available, states like Georgia and Texas are likely to draw maps that seek to entrench Republican rule as much as possible. (Democrats also engage in gerrymandering, but blue states are more likely to use independent commissions to draw district lines, or to have other safeguards that limit partisan redistricting.)
Gerrymanders can potentially make the fight to control a legislative body all but impervious to the will of the voters. In 2018, for example, Democratic candidates for the Wisconsin state assembly received 54 percent of the popular vote, but Republicans won nearly two-thirds of the seats.”
