Will 2018 be too late?

I believe you are absolutely correct. I said as much when I linked to that same article in another thread:

And, no, minority voters will not think far enough ahead to make sure they have photo i.d.s. That is something that grass-roots Democrats will have to make a high priority in the next two years: making sure that every Democratic voter has whatever s/he needs not to be turned away at the polls.

I believe the Republicans absolutely have as a goal to curtail free elections and make as sure as they possibly can that Democrats remain the minority pretty much forever. I only hope they fuck up so badly that so many of their supporters change sides that even their dirty tricks will not keep them in power. But people are generally so stupid and apathetic that I don’t have [del]much[/del] any hope.

ETA:

That’s the plan.
