Question

On January 30, 2015, the Los Angeles Times ran an online poll on its website and asked readers the question, If the NFL comes to Los Angeles, which team would be the best fit? The St. Louis Rams, San Diego Chargers and Oakland Raiders are all on year-to-year leases, unhappy with their current venues, and mulling a possible relocation to L.A. Readers clicked on one of three buttons to vote: a picture of the Oakland Raiders logo, a picture of the San Diego Chargers logo, and a picture of the St. Louis Rams logo. In all, 12,212 (33%) selected the Oakland Raiders, 2038 (6%) selected the San Diego Chargers, and 22,721 (61%) selected the St. Louis Rams.

The sample size for this poll is much larger than is typical for polls such as the Gallup Poll. Explain why the poll may give unreliable information, even with such a large sample size.
