Throughout the last 30 years, there have been significant changes regarding the media that is used to reach the masses. Regarding Politics, parties have had to readjust their campaign budgets in order to reassign funds to other forms of media that were not present prior to the '90s like the internet and social media platforms.
Politicians must now enter the competition for the votes in these platforms. This is much more demanding, as the speed that information is propagated is numerous times much higher than it was before the internet. A misunderstood post may represent a significant loss in voters.
