Conservatives bought adverts on Google which moves voters away from the controversy surrounding the "dementia tax." Labour have also used this to their advantage where they have bought ads that pop up when 'dementia tax' is searched.
I think that the controversies faced by Murdoch during political events have been exacerbated by NDM. But its well within their rights as Sites such as google do not have a value of being impartial which then as a result means that they can choose whatever side they wanted without any immediate lawful backlash. This then brings into question as to how many elections have been swayed by the influence of the internet, contrastingly this may not be true considering brexit and trump were both things to be voted for despite online polls suggesting otherwise.
