Earlier quoted context omitted.
I think you're replying to a different point than the GP was making -- the "major party" you are (I assume) referencing is also the party that backs Voter ID laws, which the GP was explicitly pointing out as a solution to the problem.
It is fundamentally the same point since that party doesn't want to make it easy and free to get a voter ID. If you have to take a day off work to go to the DMV or need to pay some fee to get your ID, then requiring ID is in practice making it harder to vote. If you want to require a voter ID, it is the duty of the government to assure that everyone citizen who wants one has one.
