And because political ads had been such a big part of the 2015 election and an unexpected part of the result, and then obviously the Brexit referendum, then the Trump election as well in 2016, it felt like a fairly important thing to do, to try and reverse engineer how ads were being used. They run a more professional outfit, they run lots of ads, they spend loads of money, they fundraise quite successfully, they switch well from fundraising from big States to targeting swing States with the messaging stuff and immobilization, all that sort of stuff.
