Polltergeist - the imaginary being that appears in pollsters' minds about one week before an election who 'tells' the pollsters how the outcome of the election is changing every five seconds due to sudden last minute events like how the leader says 'Alright', or eats a bacon sandwich, or what is in some emails, or what the last poll said.
The Polltergeist appears to the pollsters at night so that early in the morning the pollsters can appear on major news outlets with something they call 'News'. After the real election, the Polltergeist returns to its home in Bullshittia where it dies of laughing until it is resurrected by the news outlets in time for the next election.
