Perhaps it is a Party Shift we are seeing. The GOP and the Democrats are one party, now, which should be called Huge Money. Perhaps we are seeing a nascent movement, out of which will come a "You Gotta Throw Us a Bone Now and Then" party.
In November, Mr. Obama will win reelection because the GOP cannot find a person to run against him who is both electable and different from Mr. Obama. Again. Mr. Romney invented socialized medicine as governor of Massachusetts. He invested heavily in deregulation while at Vulture Capital. He and Mr. Obama disagree about the size of tax cuts for the rich and corporations but not about the cuts themselves.
One party. Huge Money. Super-Pacs. Free speech but at a huge cost.
Perhaps the Libertarians, Occupiers and Tea Partiers are the tip of the globally warming iceberg. They agree on some key areas, like foreign policy (no more adventurism) while we spend our treasure on the home front. The Occupiers want jobs, as do Libertarians and Tea Party folks. Some of their people move back and forth interchangably, with one over-arching motif. They all feel left out of the process by the Democrats and the GOP.
We have not actually seen a full party shift since Teddy Roosevelt. If he had not died, Teddy might have been president again. His Progressive Party might have made a real change in national interests prior to WW I.
Kept out of leadership (but forced to pay) long enough, even sheep like Americans will eventually decide utitility is diminishing at the margin. Perhaps all of these "movements" fueled by social networking are actually one movement. Perhaps these are the "Fed Ups."
Opinions expressed here are mine alone.
