I agree with that. If they feel that a "carpet-bagger" candidate is a better person for the job, they should be able to vote for that candidate.
Exactly so, in IL it is not unusual for candiadtes to shift districts for state offices, and even for US House races. I don't think it's happened for US Senate, but the ability of the candidate to represent me well in Washington is a very important consideration for any Congressional candidate. Part of that representation is knowledge of issues unique to my state and locale. I'll be reading press releases carefully.
