There are no more elections for Maricopa County Sheriff Joe Arpaio after his crushing defeat last month.

The 84-year-old lawman has just 21 days left in office.

He'll say goodbye at a news conference Thursday with a final blast of the debunked birther investigation he's been peddling for more than four years.

Arpaio and birther posse leader Mike Zullo promise their "newest revelations" about President Barack Obama's birth certificate.

Four years ago, Arpaio declared at a news conference: "I cannot in good faith report to you that these documents are authentic."

The six-term sheriff has kept the fakest of fake stories alive all this time.

Here's why: The birther believers have been cash cows for Arpaio.

Here's what he said in the documentary "The Joe Show": "You see the polls go (up). You'll get more money than you know what to do with."
