The Commissioner of Internal Revenue is a managerial position, not a policy-making one, although his input on the practical realities of tax collection and how the IRS is structured might well be very useful if the President was planning a big push on tax reform. But no such push has been forthcoming. Obama’s sole interest in the tax code has been to raise rates on high earners. So what was the commissioner doing going to the White House more than once a week on average?
One explanation would be the statutory involvement of the IRS in implementing Obamacare. But that bill was signed into law in early 2010. White House logs show on several occasions that he talked with White House staff about health care, but many other times no reason is given for his visit or whom he saw, which in itself is odd.
