Tend to agree with ajblaise at least to the at extent where he appears to infer that it is too early to make a unyielding value judgment (positive or negative) on the phenomenon/movement. There are many from different groups who main common theme is anti Obama and disassociation with Bush.
Corporate or other groups including neoCons are attempting to infiltrate the movement (i.e. Palin). However individuals such as Keith Olbermann with sensationalist journalism address them in the pejorative and indirectly via polarization shape the movement in the negative (and thereby indirectly creates negative associations (if not essentially invitations with the movement as well as assists the neoCons in there grasp on the GOP).
Right now I try and keep cautiously optimistic as to the change which predominately will impact the GOP.
