Why don't more people move to safe seats to run for office in the US?
Three out of eight US voters live in a congressional district represented by the opposite party of who they voted for for president. This figure is true for both Biden and Trump voters.
This makes you think safe Democrat districts or safe Republican districts would be represented by people born in other parts of the country they would not reasonably be able to win a general election in. But mostly not as far as I can tell.
Why don't more people who want to be representatives move to seats that are safe for the party they are members of?
