I may be wrong about this, but I believe that in some states, the elections for the House of Representatives in the early days of the U.S. were all done for the entire state and there were no “districts” to speak of. If a state had 10 House districts, they had ten candidates running for the House on a statewide basis.
It’s certainly possible, although I think the larger states’ reps were somewhat localized, although not formally. I do know for certain that you don’t have to “legally” be a resident of the district, only the state.
