The Tea Party was a great movement in the beginning, but when it became dominated by one national wannaprofit organization just before the 2010 elections, it pretty much died as a political movement. We had a budding impeach-Obama movement going until the largest group (Overpasses for America) filed as a Super PAC, which can receive contributions from anyone that are unlimited in size. That was when they started moving the focus away from impeachment.
There are a number of nonprofits doing fine work on specific issues. But people need to realize that nonprofits are not effective in leading a broader effort to confront Obama. A potent movement to stop and remove Obama must be done in the old-fashioned American way, as a movement made up of real volunteers, whose leaders are not paid salaries by anonymous fat-cats.
