There's a tendency in the media to play up divisions within a campaign, so such stories should always been taken with a grain of salt. But there have been a spate of articles about differences of opinion among McCainiacs on foreign policy, economic policy, and even campaign strategy. I happen to think the New York Times grossly exaggerates the foreign policy differences but an economic team including tax-cut-and-spend Jack Kemp and tax-and-don't-spend Pete Peterson does seem incoherent. But it will be interesting to see how the McCain camp's internal contradictions play out.
