Here's nimh with another polling intermezzo. Give a man his hobby.
It's no news that I'm a big fan of pollster.com, and specifically, its lovely and insightful graphs, in which all national and state polls are tracked, trendlines and all.
For example, these ones on the
Democratic race in Iowa, the
Republican race in Iowa, the
Democratic race in New Hampshire, and the the
Republican race in New Hampshire.
But sometimes I'm a bit frustrated by them. The pollster.com trendlines are extremely cautious. With good reason, but still. Even when new results come in that diverge from recent ones, mostly the trend line is just made a little more or less steep; actual "bends" or turns in the trend are made only once a three months or so at most.
Again, all for very sound methodological reasons. But I'm following these races and I see what could just be new trends emerging or turning, and they wont show up in the pollster.com trendlines because they are too tentative.
And then on the other hand, you have the day-to-day news reports that uncritically zoom in on any one single opinion poll result, and act like it proves some new breakthrough. "Romney within 4 points of Giuliani", you might have read last week on the basis of a national ARG poll. "Romney down to 8%", you might now read, based on the latest national Fox News poll. Or you might have read, "McCain in second place in New Hampshire, passes Rudy!, based on the latest CNN/WMUR/UNH poll; or, "Huckabee in statistical tie with Romney for first place in Iowa", based on the latest ARG poll - never mind that other polls have the difference at around 10%.
So, I want something of a middle way. So instead - new nimh graphics!
They feature poll averages by periods of roughly a month or two; averages that each encompass five to eight individual polls that appeared in that time. Data are all from pollster.com.
