In my experience liberals tend to have less coherent philosophies and understanding about how the world works, and more often than conservatives have "nothing matters" nihilistic beliefs, so I'm not too surprised they have more mental illness and lower happiness. They also more often advocate odd life paths (anti-marriage, anti-kids, pro-drugs, pro-transgenderism, sex-positive, polycules, etc.) that tend to result in more unhappiness.
