The Tea Party is Bigger by orders of magnitude, and much cleaner.
The global revolution lefties have drummed up many tiny crowds around the country, and are most notable for leaving large heaps of trash at their demonstration sites, as well as inappropriate fecal deposits.
They are also becoming known for their unsanitary practices and general nastiness. There has been much disruption of normal activities, to a disproportionate degree relative to crowd size, and hundreds of arrests.
Would you want these lefties living in your neighborhoods?
