Well, the poll wasn't broken down into precincts. Briggs extrapolated that the overall state difference was best explained by the variances in those precincts. But MA residents have moved to some areas of NH. In other words, the variances were for statewide tallies. It's not impossible that Briggs' and others "conclusion" (really, possibly hypothesis), that these particular precincts would best explain, is not entirely proven, either. The statewide variance could have been produced in other precincts. One thing, too, is that pre-election polls in various states late on Nov 1, were sometimes at some variance to exit polling. In Nevada, SurveyUSA was showing a strong Bush "trend" from 10/30 through 11/1. Yet exit polling seemed to show Kerry carrying the state, only 12 hours later. Vote tallies indicate he didn't, but there are some non-computer issues related to fraudulent vote-registration out there that seem to have affected the tally in Bush's favor. NH was a "battleground" state, and opinions may have "settled" in odder patterns or places than hypothesized from "logic," statistical or otherwise. The exit polling cited by Professor Freeman in his "Exit Poll Discrepancy" academic paper at U Penn cites exit polls with a fairly decent sample size for NH. I'm not sure about the OH exit poll's sample size, though. Or PA's. Most of the others, seem fairly good. Yet, you can't say, from that, that "the larger the sample size relative to the state, the more accurate the exit poll was." IA's was pretty good-sized, as was MN's and NH's-- yet were off quite a bit. It helps if you expand a couple of Freeman's 11 states out into hundredths of a percent. They look closer to the exit polls in some states that way. For example, CO: Freeman: "Bush predicted 49.9% Kerry predicted 48.1%" "Bush tallied 52% Kerry Tallied 46.8%." Expand this out to hundredths: State tally: CO: 51.957% Bush; 46.87% Kerry. In other words, Bush LESS than 52%, Kerry NEARLY 47%. While this is off, pre-election polls kept showing Bush with a 4 or 5 percent lead in CO. I mean, there's no need to exaggerate the idea that polls in general weren't suggesting this. To some extent, you COULD argue that some recount would almost validate the CO and a couple of other polls by getting it closer. Yet, it's also true that this only works well with just a COUPLE--not ALL--of Freeman's cited states. Cell phones and "no call" lists have been mentioned as affecting pre-election polls. Maybe cell phones also impacted on exit polling. The latter is, of course, just totally wild speculation. Just don't assume that, because someone was young and on a cell phone coming out of the polls, they were a Kerry voter! After all, cell phones are fairly unpopular with liberals in the NE. There are also things like last minute things to be considered. For example, I wonder whether the exit polls didn't ere in the other direction here in AR. I mean, when Clinton started campaigning for Kerry here in the state, it was in the last 18 hours before 11/2. Polls showed Kerry on an upswing from over 46%, Bush on a slight decline from just below 51%, right at the last minute. I think it might have gotten closer than that 50.8% to 46.7%, therefore. Clinton's active campaigning for Kerry didn't happen for Gore--at Gore's campaign's request. This helped bridge some gaps in the Demos here. Yet, little doubt of the outcome, just the numbers. That suggests that the exit polls may themselves have been too conservative sometimes--and that vote tallies are REALLY in "error" from what was cast, in some instances.
