While it's difficult to imagine our country headed toward dictatorship, perhaps we'd simply invent a 'new' form...minus the Musolini(sp?) figurehead.
My hope is that a state (any state) will take the feds on, over an issue that will clearly expose their (feds) over-reaching powers. Once that happens, their house of cards would begin to fall. Barring that, the threat of secession should remain an option, as we retain that right. Our children deserve at least this much and our legacy should not include the shameful lack of resolve to make it happen.
Trouble-shooting what's wrong with this country isn't a problem. Getting people to wake up and vote for the solutions is.
If the two major parties are enthralled with communitarianism/huge central governmentalism, in the belief that it'll buy them votes (see: robbing the community chest above), then the only answer is to introduce a different party and expose them for what they are. Perhaps an even more radical idea: Propose that all state and federal employees be banned from voting in elections as a safeguard against 'porkerism'.
