Will history repeat itself?

Meanwhile, Peggy Noonan doesn't agree with me that John McCain's campaign is taking on the aura of Harry Truman's in 1948- though she does think that Barack Obama is looking more and more like Tom Dewey.

She also notices that something in the dynamics of the campaign has changed in the last four weeks- and that things haven't exactly shifted in Obama's favor.

Meanwhile, Tobey Harnden at Real Clear Politics notes that McCain has caught on to the secret that enabled Harry Truman to pull off that upset: make the campaign be about your prissy, self-impressed opponent.
