All the handwringing because the orange man won the election. The political ads were fine decades leading upto 2016. Before you down vote me prove my assertion is incorrect.
The situation is even worse in countries like the UK which had somewhat-regulated advertising, suddenly being exposed to the Wild West. Reports were going around this morning of the Conservative party buying a misleading ad pointing at their own "labourmanifesto.co.uk". Basically as legitimate as a banking phish site.
Are we talking about Clinton, Reagan or Nixon? Since all of those had pretty dirty dealing in the administrations. Are you certain that people that voted for Trump expected a saint and didn't know what kind of guy he was?
If voters got what they wanted then there has been nothing gone wrong.
Your comment could've been more productive.
