Ticket-splitters poised to shake up election tallies in Pennsylvania, Georgia, New Hampshire

Many Americans will vote along party lines Tuesday, but crucial races could be decided by folks who pick a governor from one party and a Senate contender from the opposing party.

It’s known as “ticket-splitting.” Once seen as a dying trend in U.S. politics, it is expected to make a comeback.

A recent Emerson College Polling/The Hill survey in Pennsylvania found that about 9% of those supporting Democrat Josh Shapiro for governor plan to split their ticket and support Mehmet Oz, a Republican, for Senate.

Mr. Shapiro’s Republican opponent, Doug Mastriano, has struggled in his campaign and at one point urged supporters to join him in 40 days of fasting and prayer.

Meanwhile, Mr. Oz has gained momentum as Mr. Fetterman toils with questions about his recovery from a stroke in May.
