Who they claimed was polled and who did the polling:
“METHODOLOGY This ABC News/Washington Post poll was conducted by telephone Jan. 10-13, 2013, among a random national sample of 1,001 adults, including landline and cell-phone-only respondents. Results have a margin of sampling error of 3.5 points, including design effect. Partisan divisions are 33-24-37 percent, Democrats-Republicans-independents.
The survey was produced for ABC News by Langer Research Associates of New York, N.Y., with sampling, data collection and tabulation by Abt-SRBI of New York, N.Y.”
Both polls were probably taken within the NYC limits. :)
