It's my understanding after numerous phone conversations today, that Josh Brown has been seen "moving in" to the apartment he claims to have been living in since he filed for election. From what I can gather, there are several reliable witnesses (read, neighbors) who have given legal depositions stating this as a fact.
Also, a Bainbridge Island resident has filed an eligability challenge based on Josh's residence, and it's my understanding that both of Josh's Democratic primary opponents are close to doing so as well, although there is is no verification of that - yet.
Since I am in Scottsdale, Arizona at the moment and was in Detroit from last Sunday until Tuesday when I arrived here, it's been difficult keeping up with this. More as it develops.
