We often bring polling inconsistencies to light and analyze why a particular survey may be more accurate than another. Right now, however, four diverse pollsters all are showing virtually the same result in the presidential race. The conclusion: The presidential campaign, in mid-May, between President Obama and Mitt Romney, is a virtual tie.
Our first comparison is between the two polling firms that track the national race on a daily basis: Gallup and Rasmussen Reports. The latest published Gallup numbers (April 15-May 6; 3,050 registered voters grouped in five-day tracking segments) show Obama and Romney with the exact same level of support, 45-45 percent. Rasmussen, which calls 500 people every night and then groups them in three-day tracking segments, arrives at virtually the same conclusion as Gallup, but their data has Romney grabbing the smallest of leads, 46-45 percent.
Next comes TIPP, the regular polling partner of Investor’s Business Daily and the Christian Science Monitor. TIPP is the acronym used for the polling section of the TechnoMetrica Market Intelligence corporation, which claims the mantra of “America’s most accurate pollster” based upon their presidential track record in 2004 and 2008 as compiled by Real Clear Politics. According to their traditional polling interview method conducted during the May 9-16 period of 778 registered voters, the President has a slight 43-40 percent lead, certainly consistent in margin of error terms with the other pollsters just cited.
Finally, Zogby Analytics, which has in the past been criticized for being among the least accurate of pollsters, and in this case polling for the Washington Times, also returns current data that agree with the rest. According to their traditional live interview survey May 11-12 of 800 likely voters, Romney has the one-point lead, 44-43 percent. Zogby also went one step further. They asked this particular sampling segment a second ballot test question that included Libertarian candidate Gary Johnson, the former New Mexico Republican governor, who will likely be on the general election ballot in many states. When adding Johnson to the mix, the result slightly changed the Romney-Obama split; the returned result showed a consistent 44-43-2 percent division, but this time in the President’s favor.
What this tells us – because the results from four such different pollsters each with their own methodological approach pertaining to sample selection and interview philosophy – is that at the present time, the national race deserves an unequivocal toss-up rating.
