Republicans are deep into rigging elections, between voter suppression and gerrymandering.
Rich white people - no waiting. Step right in and vote. Here; Take your pick. There are 30 empty voting machines ready for you.
Poor black voters? Get in line for the 3 voting machines. Oh and 2 of them broke. We'll work on getting it fixed next year. The end of the line is a few blocks away. And I hope you brought your own water. We made it illegal for anybody to give you comfort while waiting out in the elements. We consider you the enemy and we do not give aid and comfort to enemies, neither foreign nor domestic. And neither will we allow anyone else to.
Everyone must bring their own ballot or vote in person. We made it against the law to help the old and poor by collecting their ballots for them. And watch out. Driving While Black is cause to get pulled over.
Republicans want low voter turn out. When big elections bring out a lot of voters they tend to go for Democrats.
Republicans regularly draw unfair state district maps placing as many Democrats into as few districts as possible while setting up as many Republican-favored districts as possible, just so that Republicans have an unfair non-representational presence in Congress.
If every State drew fair districts using a nonpartisan board the way Michigan does the House would be Democratic majority right now.
