" Delay still has a house in Texas and is occupying it at least at times. The only thing preventing him from being a resident of Texas is his own choice."
John Kerry has 6 fabulous houses in at least 4 different states. Is he eligible to serve as Senator in all 4 states?
It all varies by state law. Some states have stricter requirements than others, I would imagine. Kerry could -run- for election in any of those states, likely, but it wouldn't change that he was most recently elected to represent Massachusetts for one full term.
