"Talking Points Memo" has questioned the methodology of Rasmussen's Presidential Approval Index, which takes into account only those who "strongly" approve or disapprove of the President's job performance. "TPM" noted that this inherently skews negative, and reported that multiple polling experts were critical of the concept. A "New York Times" article claims Rasmussen Reports research has a "record of relying on dubious sampling and weighting techniques." Rasmussen has also been criticized for only polling Likely Voters which, according to Politico, "potentially weeds out younger and minority voters".
