I don’t think the average American voter “genuinely” thinks that they’re on a Blues Brothers-style mission from god to deliver liberalism and freedom to the world. I would be surprised if that’s even a minority view among voters.
It's indoctrination, math, and reading.
- 57% of A. think the USA contribute to peace in the world a great or a fair amount.
- Republicans and supporter think so at 82%.
- Outside of the USA, the median is at 35%.
A little important context for that poll: Globally, people believe the US is a greater threat to peace, stability and democracy than any other country.
And it's been that way in every poll I've seen since 2003.
