In White House math, certain places offer clues on outcome

ATLANTA (AP) — The Associated Press has identified 10 counties in four states that are seen as presidential bellwethers, and may provide some early answers on Tuesday night about how the White House race is unfolding.

They’re good starting points to get a sense how well the candidates’ strategies are working out. The counties are in Florida, North Carolina, Ohio and Pennsylvania — all in the Eastern time zone, where polls close the earliest.

Did Donald Trump succeed in at last winning over college-educated whites uneasy with him? Ride a wave of working-class white voters?

Did Hillary Clinton rebuild Barack Obama’s winning coalition — young voters, urban liberals and minorities — while enticing moderate Republicans?

These counties were picked on the basis of conversations with Republicans and Democrats, as well as AP’s analysis.
