I don’t know if OWS and TP have a common root...
Isn’t OWS rooted in being the left’s answer to TP? It had its 15 minutes of fame well after the TP was ramping up. I recall their clumsy and floundering attempts at trying to show that OWS was, like TP, from the grass roots...
OWS is quiet because their wing of the Dem party is in the WH. When they lose the Senate and WH the OWS will emerge and grow amongst the shocked and angry liberals. OWS is not done and gone.
