They can always pass more laws making it harder for Democrats to vote, Red States are free to alter their individual electoral policies to favor Republicans

Democrats should do this when they have power. Instead they give away several Congressional seats with redrawn maps in places like New York.

This is how I know Dems aren't serious about anything they say. They don't actually want to crush the Republicans.

But you know what they DO spend a lot of effort stopping? Third parties.
