COMPOSITE POLL QUESTION
As we are getting closer to the election, a number of polls are becoming tracking polls - being released daily, each one covering the previous three days. Rasmussen has done this all year, and I have taken all numbers for the week and averaged them immediatly prior to doing my updates late Monday/early Tuesday. Should I do the same week-long average for each of the tracking polls, thereby possibly mitigating any late week swings, or should I just use the latest result, which would be a Friday/Saturday/Sunday poll that may or may not oversample one party or another because of the days it was taken (some argue that families that are away from home on weekend polling days are more heavily Republican and thus polls on the weekend undercount them - I don't know if I buy it).

Rasmussen, Battleground and Washington Post are going to be tracking polls. All arguments welcome.
