Victor Davis Hanson makes some reasonable points in his op ed urging conservatives not to "jump ship" on John McCain. On balance, I think McCain isn't nearly as good as Hanson claims, and Obama not quite as bad. Then again, I'm not a conservative, and so not the target audience for Hanson's column.
Be that as it may, I think Hanson's appeal goes a bit off the rails when he concludes by suggesting that supporting McCain is like "trust[ing] the grating harsh voice of Gandalf detailing the dangers of Saruman rather than the mellifluous charm of the latter who in soothing tones outlines his own victimhood." To paraphrase Lloyd Bentsen: I served with Gandalf in numerous D&D campaigns; I knew Gandalf from reading the Lord of the Rings umpteen times; Gandalf was a friend of mine. And John McCain is no Gandalf.
