Much like what the government does with unemployment statistics, the following chart represents a 4-poll "rolling average" for the latest 20 polls listed at RealClearPolitics.com (plus YouGov). I also weighted the polls by their size. For example, a poll with a survey size of 1000 was weighted proportionately heavier than an 324 survey size.
Weighted 4-Poll Rolling Averages of the latest 20 Polls listed at RCP [as of Oct 14]
plus the "YouGov" poll inserted chronologically (next to last) |
