Is eminent domain a mainstream topic?

Some of the planning topics that we explore have proven to be a bit obscure. I know, because when I chat with people at public meetings or sit next to a stranger on an airplane, it takes while for me to explain why PPGIS or TDR are interesting to me. I mean they all impact your property rights and taxes, and they all might shape the places where you live or play, right? At least that's how I see it. But the citizenry has a mixed response to the issues.

So, now eminent domain comes along and is in the papers a little more often than the others on the list. I know it has some non-profits trying to fight its use and make the public aware of the tradeoffs involved. But do people really care? Or is this a fringe movement? Well, today I found this interesting piece of evidence that suggests this is a mainstream conversation.
