These fascists learned a lot from the old Soviets and their front groups. Now that they own the politicians in D.C. and state legislatures, they don't need any riff-raff as followers.
Now these billionaires are very close to destroy the country altogether after they nearly destroyed the economy with this shutdown shit.
That's why the number of actual Tea Party "activists" has declined so quickly from the heady days of 2010. Now that the Kochs and their allies and can buy their own lawmakers, they don't really need any more of those spunky "activists" dressed in tri-corner hats or people to harass liberal politicians like they did back in 2009 and 2010. They can now count on people like Pete Sessions and Ted Cruz to do their bidding on Capitol Hill. Both received ample campaign donations from groups like the Club for Growth and Koch Industries.
And right now, those bought politicians are towing the "Billionaire Party" line to a tee. They've shut down the government in what seems to be an attempt to sabotage Obamacare and prevent the media from informing Americans about how to use its insurance exchanges.
