He doesn't have a provincial health card, he's not on the voter's list and even the tax man doesn't think he's a full-time resident. His next-door neighbour has never seen him and the snow around his place isn't marred by so much as a squirrel track.
But Mike Duffy is a P.E.I. senator and as such, occupies a $130,000 per year public office in the chamber of sober second thought. Given recent revelations, the senator would be well-advised to give some sober thought to the question of whether he's been accountable to taxpayers.
Whether Duffy was entitled - and that's the key word - to $33,000 in expenses from the Senate will be sorted out by the experts. That he felt himself entitled, perhaps in the tradition of David "I'm entitled to my entitlements" Dingwall, is obvious. That's why he claimed the cash in the first place.
That's also why his own party looks like it's cutting him loose.
Reporting in the Ottawa Citizen revealed that over roughly two years, Duffy claimed $33,413 in expenses for travel and maintenance of a second home in Ottawa. Senators are allowed to claim travel and living expenses to defray the costs of working in the capital.
That's not in doubt. The question is whether or not Duffy lives in Cavendish or in Kanata. Even Duffy's personal website notes that "Mike moved to Ottawa in 1971 and began covering Parliament Hill." He's still there, more than 40 years later.
Last year, during a review of Senate expenses, questions were raised about whether Duffy actually lived in P.E.I. as he claimed, or in Ontario. The facts were collected by an internal Senate board and then last Friday, passed on to outside auditors and lawyers. That's never a good sign.
The professionals are also investigating similar expense claims by Liberal Mac Harb and Conservative Patrick Brazeau. You'll know Brazeau as the senator turfed from the Tory caucus last week after his arrest on unrelated criminal charges.
Along the way it was revealed that Duffy tried to cadge a P.E.I. health card, on an expedited basis, from the Island government. The document would help him assert his residential bona fides.
However, the P.E.I. government and Health Minister Doug Currie saw no urgency in his application and no senatorial entitlement to special treatment. And rightly so. If the senator's not living on the Island, why would he need a P.E.I. health card?
Friday, with his situation getting blurred into the Brazeau mess, Duffy issued a statement saying he has a home in P.E.I. "as required by law," and insisting that "Canadians know I would never do anything to betray the public trust."
Fine words, since Duffy is a Conservative and Conservatives claim to be accountable. That's what got them elected, as accountable alternatives to the high-handed Liberals. With Duffy's commitment to that in doubt, is he in trouble with the Tory high command?
In the public mind, Duffy's expense problems are now tangled up with Brazeau's dirty-looking case, a fact that would not be taken lightly by the Prime Minister's Office. The PM himself appointed both of them. Sending their cases to the next investigative level suggests the party is distancing itself from their problems.
And it's all about the party. Remember Duffy got the job partly for his help destroying Stephane Dion during the 2008 election campaign. That's not to say that his appointment came as a direct reward for the brass-knuckle treatment of Dion. But it sure proved Duffy's loyalty to the Tory cause.
Turns out his real Senate job is telling folksy stories at Conservative fundraisers. But you have to wonder whether he'll be in demand much longer. A lot of Conservative donors will take a dim view of Ottawa's entitlement mindset.
Duffy needs his party now, but is it there for him? His expense claims were sent to the pros at the behest of a Tory-dominated committee. If headquarters was really behind him and believed he had done no wrong, the matter would never have gone to the auditors at Deloitte.
It could be that this time, the senator is on his own.
