The only difference between the Democrats and the Republicans is suicide as opposed to terminal illness.
The grass roots movement doesn't have a political axe to grind.
By the way, eminent domain has been an issue for years.
Thanks to the internet there's allot of discussion that is moving toward rectifying abuse of eminent domain. As to other histories you mentioned, they were all before widespread Internet.
Despite a severely biased MSM amid shrieking celebrities the move towards honesty elected George W. Bush President. Of course, Swift Boat Veterans for Truth are credited too, aided by the Internet.
I appreciate the tool that the internet has provided regarding communication and exposure; however, the internet isn't required for the public to have knowledge of state/federal programs/policies/laws. Those are all a matter of public record. Before the internet, I sent a written request for information regarding proposed/enacted federal documents. There was also the telephone and snail mail. Also, I think the public was aware of the income tax, sideline taxes, and the elimination of the gold and silver standard before the internet. Again, by and large, the citizenry chose not to take the action that is required of them if they wish to maintain liberty.
