The actual influence of Cambridge Analytica - who also spectacularly failed to help Ted Cruz win the primaries - might have been greatly overstated, but the difference between this and the Obama campaign is that the latter isn't accused of breaking British data protection law with large scale scraping efforts and none of its executives have been caught on camera bragging about bribing and honeytrapping potential political challengers, and there isn't even a tenuous link between executives working for his team and alleged treasonous collusion with the uh...data mining efforts of a foreign superpower.
