The appointment of Dominic Cummings - a man David Cameron described as a "career psychopath" - as Boris Johnson's senior adviser shows just how toxic Johnson's government will be. More on Cummings here: https://badboysofbrexit.com/2017/12/22/dominic-cummings/

Cambridge Analytica whistleblower @chrisinsilico on Dominic Cummings:
"He went around & found places he could launder money through to give it to AIQ so they could overspend...You cannot call yourself a Leaver, somebody who believes in British law, & win by breaking British law."

Why the overspending? Dominic Cummings has admitted Vote Leave used AIQ to place 1.5 billion ads like these on individual Facebook feeds in the days before the referendum. All completely under the radar of the regulator.

Here's Dominic Cummings describing how he & Vote Leave used AIQ & Facebook to target carefully tailored disinformation on millions of British voters in 2016. It's beyond grim that this man is now Boris Johnson's senior adviser.

The sheer mendacity of the disinformation peddled to UK voters by Dominic Cummings & Vote Leave was breathtaking. Here's another of those dark Facebook ads, this one targeted on people identified as worried about immigration.

Incidentally, people who saw Channel 4's #Brexit: The Uncivil War might have thought Benedict Cumberbatch was overegging his portrayal of Dominic Cummings. If anything, the opposite is the case. The truth was both more complicated & much uglier.
