> doesn't prevent you from running for public office For the vast majority of elected offices, one of the most important qualifications is "registered to vote in the district you are going to represent". Most offices have some age requirement (which might be as simple as "old enough to register to vote") and extremely few had some occupational requirement (like District Attorney has a law degree/license requirement, but Sheriff has no such requirement). When I ran for office in Colorado, failing to be registered to vote in the district you represent was the fastest and most automatic way of getting thrown out of office: no trial, no impeachment, just out you go. The requirements for President are listed in the Constitution. Getting on the ballot in each state is harder as each state has different requirements.
