#' Pew Research Center poll on health care, including question variants
#'
#' For example, Pew Research Center conducted a survey with the following
#' question: "As you may know, by 2014 nearly all Americans will be required to
#' have health insurance. People who do not buy insurance will pay a penalty
#' while people who cannot afford it will receive financial help from the
#' government. Do you approve or disapprove of this policy?" For each randomly
#' sampled respondent, the statements in brackets were randomized: either they
#' were kept in the order given above, or the two statements were reversed.
