The fact is the Republican Party wants to make it nearly impossible for people to vote.
You can't just make it impossible for one party to vote. There are no Republican lines and Democrat lines.
It is true that Republicans don't want to make it easy to vote, and that's a good thing. If you don't want to put any effort into voting, it probably means you don't care about it that much. If you don't care about it that much, it likely means you know little about WTF you're voting on.
If only politically knowledgeable people could vote our government would be in a lot better shape. We would end up with a lot better leaders. But as it is today, we have too many Obama Money people voting; people so ignorant of our country they don't know which side is up and which side is down.
If it were up to me, you would have to take a very simple test before being handed a ballot. Nothing very difficult, just a simple basic test to see if you have the most minimal knowledge of what's going on.
