Yes, I agree michael, but although the "Tea Party people" are certainly grass roots, they have little political leverage and their platform does not include any radical change to the system.
Mr Sanders may be well intentioned, but will be rendered ineffective even if he does manage to gain the Presidency.

You are really between a "rock and a hard place" and it must be extremely frustrating for GENUINE radical thinkers like yourself.

While the huge political chasm survives between faux left and faux right nothing very much can be achieved.
