Red states require more migration because people die quicker in red states. Conservative policies lead to early deaths. Blue states are sanctuaries from those policies.

>The October report found that if all states implemented liberal policies on the environment, gun safety, criminal justice, health and welfare, labor, marijuana, and economic and tobacco taxes, more than 170,000 lives would have been saved in 2019. On the flip side, if states went with conservative versions of those policies, there would have been about 217,000 more deaths that year — “the equivalent of a 600-passenger airplane crashing every day of the year,” the study said. https://www.reddit.com/r/politics/comments/znfhsz/can_politics_kill_you_research_says_the_answer/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=share_button

>In Trump states, the rate was 8.20 murders per 100,000 residents. In Biden states, the rate was 5.78 murders per 100,000 residents. "These Biden-voting states include the 'crime-is-out-of-control' cities of Los Angeles, New York City, Chicago, Detroit, Philadelphia, Portland, Baltimore, and Minneapolis,"

>"Jacksonville, a city with a Republican mayor, had 128 more murders in 2020 than San Francisco, a city with a Democrat mayor, despite their comparable populations. In fact, the homicide rate in Speaker Nancy Pelosi’s San Francisco was half that of House Republican Leader Kevin McCarthy’s Bakersfield, a city with a Republican mayor that overwhelmingly voted for Trump."
