Almost all Haley supporters are voting for trump.
A missing sliver MAY be the number of NC Dems who changed registration to Independent so they could vote in the GOP primary (with a contested Dem primary at the top). Not a huge number but those may well be “hidden” Harris voters in the Independent cluster.
“… There were 2,424,069 million registered
Democrats and 2,309,357 registered Republicans in the state as of October 12, one day after the deadline to register online or by mail. North Carolina residents can still register to vote at early voting sites.
But unaffiliated voters make up the largest voting group in North Carolina, as 2,925,342 people do not identify with any party
… In a November 7, 2020, report, Democrats held an even larger edge, with 2,644,050 voters identifying as Democrats, compared to 2,233,007 as Republicans. At the time, 2,452,783 voters were unaffiliated. Trump won North Carolina by 1.3 points that year. …”
