I think it's kind of cowardly to only read things from sources that you agree with. As for his argument that Republicans are trying to overturn votes that are already counted, I tend to believe that it's either pretty thin or very shortsighted.
But I'm personally a huge fan of requiring voter IDs for all, but I do think they should be free or low cost. I also am a proponent of the Republican efforts to get rid of ballot harvesting at the state level. I think that is probably the easiest way to commit voter fraud, and it's kind of a despicable practice, imo.
