Votings lines: Is the press going to ask why?

Stories about early voting lines in several states that have extended four, six, and eight hours are remarkable. I've been voting for the better part of two decades and we can't remember seeing anything like the widespread phenomena that's unfolding. 

As Rachel Maddow noted in a recent commentary on MSNBC, on the one hand it makes you proud that citizens would endure that kind of hardship (and let's face it, is it) to vote. (Her other point was that the lines constitute a modern day poll tax.)

But what I can't understand is why isn't the press drilling down on the very simple question of why? Why is this happening? Is it simply the popularity of early voting, and does the process of early voting take that much longer?

That would seem to be  journalism 101. But so far, all I've read and seen are a lot of can-you-believe-how-long-these-lines-are? reports. What I haven't seen is much insight into how and why this has suddenly became a country where, at least in some sizable pockets, it can take an entire workday to cast a single vote. (Or do political journalists only do horse race and personality-based campaign reporting?)

I'm not suggesting there's any dark conspiracy behind the long lines. Just that the state of voting in this country sorta resembles a joke, and that the press ought to treat that as a serious news story, instead of dismissing it the way today's WSJ did. In a news article about possible snafus that may unfold at the voting place tomorrow, the Journal listed one possibility as, "The lines are long." The next line in the Journal article read, "Tough luck."
