CHARLOTTE, N.C. (AP) — Union members in North Carolina and their leaders are embarking on an eight-week sprint to help elect candidates from the top of the ticket to down-ballot races they say back pro-worker policies.

The AFL-CIO scheduled a Saturday morning rally in Charlotte for their Labor 2016 electoral program, followed by a four-hour door-to-door canvass designed to promote Hillary Clinton, U.S. Senate candidate Deborah Ross and other candidates they consider allies.

The program will include direct mail, online ads and efforts to protect voter rights. The national AFL-CIO is bringing staff to North Carolina for the effort and spending more than double compared to what the group spent in the state four years ago.

Saturday’s speakers include David Cox, a North Carolina native and president of the American Federation of Government Employees.
