a) I deny this information is that useful. If Obama wins, I bet he got most of the anti-war vote! I don't need an entrance poll to tell me; b) Network polling place surveys have a history of humiliating error. Ask Presidents Gore and Kerry; c) The information, even if accurate, is likely to be deceptive. If Obama does get 53 percent of the antiwar vote, that might mean antiwar voters shopped around and found Obama the most anti-war of the candidates. Or they might have liked his smile. They might even have liked Obama first, before thinking about the issues, and then become antiwar voters because that's what Obama talked about; d) Mainly these unenlightening little correlations let network news divisions fill time--because the real news (who won) comes at an inconveniently late hour and then only takes about 10 seconds to report; e) The conceit of the "caucuses" is that voters meet, argue with their neighbors, listen to speeches, and then vote. But the entrance poll records their preference before the arguing and speeches; f) Worse, the entrance poll results threaten to have a Heisenbergish outcome-distorting effect, since they may be known before the caucus votes are finished and will instantly flash on everyone's Blackberry, cell phone, etc.. If Obama is barely edging out Edwards in the (possibly inaccurate) entrance poll, with Hillary third, will Hillary order her supporters to switch over to Edwards in order to deny Obama a win? I don't think that's too far-fetched. ...
Backfill: The networks wouldn't have to resort to a questionable "entrance" poll if Iowans voted at normal hours using, say, easily-countable ballots. But that's not the Iowa way. For a preview of the state's near-identical vote problems from four years ago, see "The Four Votes of Iowa." Key point:
Iowa only gets its moment of cynosure, in other words, because its system is too f---ed up to be a primary.
If it were a straightforward "primary," after all, then it wouldn't be allowed to precede New Hampshire.
All this might be excusable if Iowa Dem caucusers had a long track record of sound judgment. Alas, ...
