The Washington Post's "The Fix" has a fascinating analysis on polling data. In an earlier post, I mentioned that some had concerns about polls conducted by Rasmussen. Chris Cillizza goes through the pluses and minuses of polls conducted by Rasmussen and Survey USA. The main sticking point involves how they do the interviews. Rasmussen and Survey USA don't use live interviewers but a "single, digitally recorded voice."
Anyone interested in polling should give it a look.
