That's actually pretty common. As Scouts, we invite politicians to speak about government, policy, civil service or present awards. They're not required to represent the district of the Den or Troop. My Troop was based in Aurora, we hosted Denver City Council members, State Senators from Weld, Pueblo and Evergreen, even a US Senator from Kansas and New Mexico. Sometimes it had to do with who an adult leader worked with, sometimes it was a politician accepting the invitation of a Scout. It's a good way to learn about various aspects of government.
