RALEIGH, N.C. (AP) — A federal court decision last week striking down North Carolina’s law requiring photo identification to vote could make it easier for people to cast ballots this fall.

But this and other changes to the state’s voting rules also create an election year disruption that could confuse voters as they wind their way through the electoral process.

Photo identification was required for the first time in this year’s primaries, but barring a legal delay, it’s no longer mandated. Early voting will also be extended to 17 days, up from 10. It also means seven additional days of same-day voter registration during early voting.

State election officials now must scramble to retool their training programs and manuals for precinct workers.
