“Pollster Mark Blumenthal reported that “It is important to note that what ARG does ... is very different from the way other pollsters ask about party ID. ARG asks about party registration in some states, party identification in others and then combines the two results into a single variable. Whatever the merits of this approach, the results will not be comparable to those of other polling organizations.”[3]
In 2004, Gallup interviewed ARG about a poor prediction (22 points adrift) in the Maryland Democratic primary and found their “likely voter” model was “based on just the one question, [which] is a relatively simple approach to classifying voters.”[4]
ARG was criticised in 2007 for only using landline respondents, which they justified by arguing that cellular phone users, who are mostly younger people, mostly “don’t vote”.[5]”
