Liz Mair thinks Governor Whitman is off in assuming John McCain cannot win the nomination.
I think Governor Whitman is close to the mark, though. McCain has several big albatrosses around his neck. The biggest is campaign finance reform - and his continuing campaign against free speech (albeit that is not what he intends). Others will include the Gang of 14, his alignment with gun-control advocates on gun shows, and his opposition to the President over detainee treatment. The zampolit wing will also hammer McCain for his public stance in favor of a comprehensive bill (one case where he is correct to buck the base).
McCain is the media's GOP front-runner for 2008. The real front-runner for the GOP nomination is probably Rudy Giuliani or Mitt Romney. Any of the three would be good Presidents, but I will admit I lean towards Romney at this time.
