This RCP analysis and accompanying chart is very helpful, reading in part: “The real story, post Labor Day, has been the solid pop for Fred Thompson following his formal announcement last week, the resurgence of John McCain, the small but steady improvement for Mike Huckabee, the lack of any national follow-through for Mitt Romney following his bounce after the Iowa straw poll and the continued stability of support for the GOP front-runner Rudy Giuliani.” Contrary state polls like the Florida one linked to earlier suggest all this may be in huge flux but we’ll certainly know in a month or so whether McCain and Thompson are in a dog fight with Rudy for the lead. One caution: for obvious reasons the Romney camp continually points out that the primary system is a state by state race and not a national primary. True, but maybe less so this year in light of Super Duper Tuesday.
