Lewis Ranft: They probably won't be with this election. Many will "pretend" to be Obama supporters because they are afraid of being called racist, but will actually vote for McCain (Bradley effect). Also, polling methods vary widely (depending on who's doing the polling) and sample sizes allow for great variability.
Pasquale Pollet: i don't know
Russ Kiernan: They randomly contact a small number of people, usually in the range of 1,000 to 1,500. Considering the total population of America, the chances that someone you know would be called are very small.
Voncile Slaubaugh: yes it can
Michel Mccaulley: I don't know, but they sure scare the heck out of me. Watch on election eve, it will be a statiscial tie, ...guaranteed. Then we will see how many who say they are going to vote for Obama actually will.
Elaina Adolfson: i don't know. this election i have had a pollster call, and some people show up at my door. both were obama supporte! rs. i just told them he had my vote to get rid of them.
Autumn Vacio: They ask a random cross section of people in each state. They're accurate-ish, but don't take them as read. Use them more as a rough guide of who's ahead, not anything else.
