Lehigh County anchors Pennsylvania's Lehigh Valley and has shifted steadily toward competitive territory over the past decade, with its mix of mid-sized-city voters in Allentown and growing Latino population reshaping its presidential margins.

The county's recent history is a story of close margins. The Democratic margin reached thirty-six points in 1912; the Republican margin reached fifty points in 1928. Most other elections have been decided by single-digit points.

Lehigh County's demographics — a population of 378,792, a 62% non-Hispanic-white share, a median household income of $80,079 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Clark County and Caledonia County.
