Polls as part of politics have become theatre and it was interesting to see a post this week from Poll Bludger on a poll by Essential Research when people were asked how they voted in 2010:
Respondents were also asked who they voted for in 2010, an exercise which is generally recognised as being blighted by the tendency of some to mis-remember having voted for the winning party. Sure enough, once “didn’t vote” and “don’t know” are excluded, the results are 44% for Labor, 42% for the Coalition and 8% for the Greens, compared with election results of 38.0%, 43.6% and 11.8%.Some differences here apperar to be outside the margin of error for the poll. There were 4% of people who didn't know how they voted in 2010 and 7% polled who didn't vote. However, a statistically relevant proportion of them polled were deluded on who they actually voted for last election?
