Is a class action suit against the GOP possible?

There is little to no doubt that the GOP-driven endeavors to block voting for legitimate (and likely Democratic) voters in a number of states has nothing to do with voter fraud and everything to do with trying to tilt the odds in their favor for the next election.

So I, with my complete lack of education in the law, find myself wondering whether disenfranchised voters constitutes a class in and of themselves and they can actually sue the entirety of the Republican party in general and in specific the legislatures in the nine states that are complicit in this indisputably partisan endeavor? Of course, the whole point of this exercise is to target the poor and those least likely to have the resources to defend their rights, so it’s not likely to happen. But I still wonder if it’s possible?
