Two North Carolina congressional candidates are still unsure of what the future holds, and they won't know until 6th Congressional district voters have their say in the July runoff for the Republican nomination. This week, host Donna Martinez talks with candidate Mark Walker about his background and views, and Walker discusses what distinguishes him from his GOP opponent, Phil Berger Jr. Then we turn to perspective on North Carolina's U.S. senate race -- the race can may determine whether Democrats retain control of the Senate. NC State political science professor Andy Taylor explains the dynamics of the race between Democratic incumbent Kay Hagan and her GOP opponent, N.C. House Speaker Thom Tillis. That's followed by an update on the "Moral Monday" protest movement, which has returned to the General Assembly grounds to express members' disagreements with the Republican-led chambers. After repeated warnings by police, more than a dozen protesters were arrested for refusing to leave Speaker Tillis' office. You'll hear Gov. Pat McCrory's view of the incident in an interview with Henry Hinton of WTIB in Greenville. Next is an update on key N.C. Senate races to watch in November. Rick Henderson of Carolina Journal tells Martinez that several incumbents are facing tough challenges. The two also discuss the latest on Sen. Hagan's aggressive campaign against rival Tillis as the Speaker presides over House proceedings.
