By STEVE KARNOWSKI MINNEAPOLIS (AP) — State election directors from across the country voiced serious concerns to a top U.S. Postal Service official Tuesday that the system won’t be able to handle an expected crush of mail-in ballots in the November election. Steven Carter, manager of election and government programs for the postal service, attempted to reassure the directors at a meeting in Minneapolis that the system’s Office of Inspector General will publish an election mail report next week containing “encouraging” performance numbers for this year so far. “The data that that we’re seeing showing improvements in the right direction,” Carter told a conference of the National Association of State Election Directors.
