They are relying on a law in Alaska that says a candidate running for office cannot be subpoened.The claim is since the investigation involves Sarah that applies to her husband and her staff as well.That will never stand up legally but since it would be up to the legislature they say to make that finding and they don't meet again until January that will be good enough for this to be delayed past the election.Her husband it seems by many is very inolved in the operation of the governors office,gets copied on e-mails,attends official meetings etc. Even saw a republican interviewed in Alaska who said she was shocked at how he stayed in a meeting she was having with the gov and that she had never seen a spouse do that before.
And on the spousal priviledge against testifying agianst a wife,I guess it's possible he could use that but it sure wouldn't look good,another reason they don't want that to happen before the election.
