Former North Carolina state Sen. Cal Cunningham (D) announced on Monday that he will challenge Sen. Thom TillisThomas (Thom) Roland TillisGOP senators unveil bill designating Taliban as terrorist organization Without major changes, more Americans could be victims of online crime How to fix the semiconductor chip shortage (it's more than manufacturing) MORE (R-N.C.) for his seat in 2020.
Cunningham, a veteran of the Iraq War who served as an Army prosecutor, is the third Democrat to enter the race against Tillis, who also faces a GOP primary challenge.
Tillis is seen as one of the more vulnerable Republicans in the Senate, as Democrats are hopeful their presidential candidate could win the Tarheel State.
Former President Obama in 2008 is the only Democrat to recently win the state in a presidential election, and he was defeated there four years later.
Cunningham is leaving a more crowded race for lieutenant governor to join the Senate race. He previously ran in 2010 for the U.S. Senate, finishing second in the Democratic primary. He received support in that race from the Democratic Senatorial Campaign Committee.
In his announcement video, Cunningham said he would fight for an economy that worked "for everybody, for the health care that each family deserves, and to reform the corrupt political system in Washington."
He cast his decision to change races as one motivated by a desire to effect positive change in people's lives, saying people on the campaign trail had asked him about entering the Senate race, according to The Associated Press.
Cunningham joins North Carolina state Sen. Erica Smith and Mecklenburg County Commissioner Trevor Fuller in the Senate race.
