Ron Paul won 45 percent of the vote in a straw poll in California over the weekend, and his supporters are beside themselves with joy. What I can’t figure out is why such bright people are so fooled about something so meaningless.
There are three kinds of political polls. (Well, four, if you want to count election day voting.) Let’s talk about what they are and which ones matter, because many very bright people don’t understand which ones are potentially worth getting excited about.
The first of the three is the opinion poll with a statistically valid, randomly selected sample of the likely voting population — and this is the only one that matters. These are the polls done by the big polling organizations such as Gallup and Pew and various others done for major media outlets. These are expensive to conduct, but they tend to be very useful and reasonably accurate. The results can be skewed slightly one way or another by the wording of questions or by the selection of the random sample. Various pollsters make slightly different assumptions and calculations about who likely voters are going to be, but their results tend to be reasonably accurate — especially if you average all the polls.
Right of secession? In a sane world, we could talk about it in 2011 without talk of slavery
Yes, I truly appreciate your flaws; they point the way to your worth
I wasn’t allowed to express need, so I’ve spent life traveling alone

Health risk and social costs make drinking alcohol a very poor risk
If you’re out of place somewhere, nobody’s going to be very happy

Life choices: What’s important enough to spend your life doing?
We project an image for others, but few see us as we really are
Will the last journalist to leave newspaper business turn off lights?
