“Condescension Bias” is generally most noticed when you recognize and accept the political structures within the U.S. are comprised of private entities (political parties) who approve of, or disapprove of, the voices they allow into their group.

The DNC and RNC are private clubs no different from any other private organization or corporation. Thanks to the 2009 Citizens United decision the funding for the private club shifted from necessarily needing voter support, a source of historical angst, toward unlimited funding from Wall Street interests.
In essence, with the support of the electorate no longer necessary, the club no longer was forced to manufacture the illusion of inclusion. The elites can now be as exclusive as their ideology demands.
As a direct consequence, U.S. Political representation radically shifted from away from giving the impression of a representative democracy – to an open and visible oligarchy of monetary interests who now select candidates. Those corporations now openly set the political agenda for their approved club applicants, the electorate are irrelevant.

…. Thus begets the rise of the Rebel Alliance.
