Factual Science and research methods

In 2012, Obama beat his polling by 2 or 3 percentage points in almost every swing state.

Mostly true True in substance, wrong in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Compare Obama's 2012 certified margin in each commonly defined swing state (e.g., CO, FL, IA, NV, NH, NC, OH, VA, WI, PA, MI) with his final polling-average margin (e.g., FiveThirtyEight, RCP or comparable averages). True: in nearly all swing states (all but one or two) Obama beat his polling margin by roughly 2–3 points (about 1.5–3.5 counts). Mostly true: he beat his polls in nearly all swing states but the typical size was somewhat off (e.g., about 1–2 or 3–4 points on average), or a few more states fall outside the range. Mixed: he beat his polls in most swing states but the size varied widely, with only about half in the 2–3-point range. Mostly false: he outperformed his polls only in some swing states, or by much smaller amounts (under ~1 point typically). False: Obama generally matched or underperformed his swing-state polling.

    “He also beat his state-by-state polling averages by around 3 points, with his final margins improving upon the RCP averages in all 11 states.”

Reasoning

RCP final averages compared with results show Obama beat his polling margin in Florida by about 2.4 points (E2, consistent with E9), and in three other battleground rows on the same page, which the quoted rows do not name, by about 1.6 (E3), 3.6 (E4) and 3.9 points (E8). A post-election blog shows similar gaps in Iowa (3.4), Nevada (3.8) and Michigan (5.5), with Ohio the only swing state where he did not beat his polling (E9, E10). A separate outside report also says Ohio was the exception (E11), and another analyst says he outperformed the polls in most battleground states (E5). He beat his polls in nearly every swing state except Ohio (E10, E11), but several gaps were above the 2–3 point range, for example Michigan at about 5.5 points and Colorado and Nevada at about 3.8 (E9). This fits "mostly true" under the criteria.
