They can send fake letters to everyone and look like there's millions of activists - when in fact it's three paid professionals in a 'war room'... Those three people and their political bosses can't have a 'Tea party'.
There's two sections to the 'hate' section of of liberal elites. 'rent a crowds' - where Union goons, ACORN members, citizens working off court ordered speeding tickets, protests.
And the street riots bunch - bored citizens who think it's still 1968 - who want entertainment and excitement. They can't do 'Tea Party' either...
Just like their ideological "father".
