Can we put a strap-line under each parties name that tells us the raison d'etre for that view of politics? I don't mean an essay. On the other hand nor do I think three-word slogans such as "The People's Party" explain what they are hoping to be in power for.
This is my offering so far:
Conservativism Emphasises traditions and relies on the individual to maintain society.
Liberal Democracy Belief that freedom is impossible without equality, and that governments should promote egalitarianism by providing education and health care supported by taxes.
Libertarianism Believe that taxes are bad and that people should provide for their own education and health care.
Socialism An economic and political system where the community or state owns the general means of production (i. e. farms, factories, tools, and raw materials.)
Social Democracy Similar values to socialism, but within a capitalist framework. Supports a competitive economy with money while also helping people whose jobs don't pay a lot.
Greenism/ecopolitics Aims to foster an ecologically sustainable society often, but not always, rooted in environmentalism, nonviolence, social justice and grassroots democracy.
I suggest we try and keep to three(ish) lines for each. You will see I had to divide up the possible aims of the Labour Party - but that is because I see it as divided - others may not.
Good Luck and in my case ... thanks to the Honourable Member for Google.
