Usually, any “extremist” movement has less than 10% support.
That would be the outright communists/socialists.
The TP folks have huge support. They are not “extreme” in the least.
“Jul 2, 2010 ... Thirty percent of Americans, on average, identify as Tea Party supporters “
I remember the Kerry entourage trying to connect with the “common” people during the 2004 presidential campaign. They stopped the campaign bus by a fast food restaurant, made a public show of going in and buying bags of burgers or tacos, and once on the bus, threw it all out so they could eat gourmet brie and watercress sandwiches.
And that number will only grow.
