Why Are Liberals Healthier?

Why are liberals healthier?
Vegetarianism is scorned by conservatives. Cigarettes are promoted by conservatives.
Then there’s pollution, mercury, arsenic, national parks, clean water, lead, even SUVs, which are more dangerous than regular cars. And don’t leave out processed foods.
Oh yeah, health care. Liberals are for it.
Is “conservatism” ENTIRELY about being duped by corporations to do things that are against your own interests? It sure seems that way.
