These figures are approximate as I don't know the number of adults in Chesham and Amersham that haven't registered. I've used the national figure. Approximately 11.48% of the adult population don't register (source below). So I've used this figure for Chesham/Amersham. Electorate = 72,828. So using this figure, this means that the potential number of voters is 81,188. LibDems' vote = 21,517, % of adult population who voted = 26.5%.
At the last election, using the same principle, Conservatives received 24.93%, Labour 18.28% of the adult population.
Therefore, the majority of people don't vote, the vast majority of the people don't vote for (or support) the ruling party. Although the 'ruling' party doesn't rule, it administers capitalism until the next election when a different party (sometimes the same) party takes over the administration of capitalism. Capitalism and its state continues. It's a fraud, nothing to do with democracy.
December 2020, there were 46,906,270 Parliamentary electoral registrations
Can't find a figure for the adult population for December 2020, but in December 2019 it was 52.7 million. This had increased by 289,000 in one year. That's an increase of 0.5484%. So I've added that to the figure, giving an estimated adult population of 52,989,000. Therefore registered voters = 88.521% of the adult population. source 2
Is there a flaw in my calculations – and in my reasoning?
