Pat Murphy has a habit, almost invariably, when writing about John McCain, of bringing up Sen. McCain's association with the Keating Five scandal of the mid-1980s. The implication is always that he is in some way dishonest.
I ran across a quote this week from the lawyer for the Senate Ethics Committee at that time, Robert Bennett, a Democrat. "I investigated John McCain for a year and a half, at least, when I was special counsel to the Senate Ethics Committee in the Keating Five ... and if there is one thing I am absolutely confident of, it is that John McCain is an honest man. I recommended that he be cut out of the case, that there was no evidence against him."
Further, the only reason he was not dropped from the investigation was, as The New York Times (that bastion of conservative thinking) reported: "Sen. McCain was the only Republican embroiled in the affair and the Democrats on the panel would not release him."
So, in the future when you read Mr. Murphy's attacks on the senator from Arizona, or anyone else for that matter, take it with a mountain of salt and investigate it yourself.
