Three-quarters of Americans say they oppose the US attempting to take control of Greenland, according to a new CNN poll conducted by SSRS, indicating that President Donald Trump’s push to expand America’s territory faces stiff headwinds with the public.
Summary: Republicans are 50/50, everyone else is strongly opposed.
The poll doesn’t say anything about military action. The Qunnipiac poll shows that when the question explicitly includes military action, opposition is over 90%: https://abcnews.go.com/Politics/us-voters-widely-opposed-taking-greenland-military-force/story?id=129280864
