I liked the image I saw a few days back. Conservatives will play to your base needs (food/water, shelter, family), while Liberals/Socialists expect selflessness and assume all your needs are already met, including self-fulfilment.

Especially in the poorer and war torn regions of the world, the former is magnitudes more appealing. If non-extremist groups want to have a chance, they need to cover the bases first.
