He still owned property there so it was easily done. He was stick technically a resident
Iirc there wasnt time to get a judicial ruling at the time
Nope, Cheney was a bona fide, voting Texas resident but quickly changed his residency and then registered to vote in Wyoming when he knew he would be chosen by W to be his veep. Where Cheney owned property had nothing to do with this except to make things a little more palatable to the public i.e., that he at least owned some property in the state he jumped back into, LOL.
