RALEIGH, N.C. –  Thom Tillis got the stage alone Tuesday night in North Carolina's tight U.S. Senate race, the only candidate on a statewide television program in which he discussed views on abortion, global climate change and differences with absent Democratic incumbent Kay Hagan.

The program initially billed as a debate between Tillis and other candidates turned into a one-hour conversation with him and two reporters, as well as responses to emailed or recorded questions from the public. Hagan announced over the summer her decision not to participate, while Libertarian Sean Haugh didn't meet a 15 percent polling threshold to join Tillis.

An empty seat was placed next to Tillis at the Time Warner Cable News studios in Raleigh as the state House speaker answered questions on many topics as the start of early in-person voting Thursday neared.

"I'm disappointed that Sen. Hagan's not here," Tillis said in a closing statement in which he repeated themes from their previous three televised debates with Hagan in which he linked her closely to President Barack Obama's policies.
