"We know a lot about President Obama, and I think the idea that he would want the IRS used for retribution — we have no evidence of any such thing."

Says Carl Bernstein, declaring that the Obama administration's IRS scandal is not Watergate. 

"In the Nixon White House, we heard the president of the United States on tape saying 'Use the IRS to get back on our enemies."

The link goes to Politico, which doesn't close the quotation marks around "Use the IRS to get back on our enemies," and doesn't link to specific Nixon quotes found on the Watergate tapes. It's strange to put quotes around that if it's not a quote. Here's the Wikipedia article "Nixon's Enemies List," which doesn't quote any Nixon remarks. It does have the truly shocking John Dean memo that asks "how we can use the available federal machinery to screw our political enemies." Politico needs to close the quotation marks and link to the quote or take away the quotes and add some material about how Nixon never said that and perhaps Bernstein — the wheeled-out old authority on Watergate — meant to say John Dean when he said Nixon.

Now, as to we have any evidence that Obama would want the IRS used for retribution, Obama once joked about using the machinery of the IRS against his enemies:

At his Arizona State University commencement speech [in May 2009], Mr. Obama noted that ASU had refused to grant him an honorary degree, citing his lack of experience, and the controversy this had caused. He then demonstrated ASU's point by remarking, "I really thought this was much ado about nothing, but I do think we all learned an important lesson. I learned never again to pick another team over the Sun Devils in my NCAA brackets. . . . President [Michael] Crowe and the Board of Regents will soon learn all about being audited by the IRS."
