BLOVIATORS

To bloviate means "to speak pompously and excessively" or "to expound ridiculously". A colloquial verb coined in the United States, it is commonly used with contempt to describe the behavior of politicians, academics, pundits or media "experts," sometimes called bloviators, who hold forth on subjects in an arrogant, tiresome way.
Think of Rush, Glenn, Ann, Michelle & Sarah.
That's the truth, just listen to them !
