-Quite a few False Dawns. 'Webcameron' YT Channel in 2010 was just a Publicity Stunt [Given more Credit than it Deserves] [Although this did allow the Conservatives to make Cameron to seem like a Fresh, Dynamic Leader] -Conservatives had Halved their Spending on Facebook during 2019 -Social Media seems to be unable to win over New Voters. Instead it just reinforces People's Views. So it acts as an Echo Chamber
