Keith Crisco, a Democratic congressional candidate who battled former American Idol star Clay Aiken for his party's nomination, died unexpectedly Monday.

"[E]arly information indicates he suffered injuries from a fall around 1 p.m. at his home," the Courier-Tribune reports. Crisco was 71 years old.

The results of the election have not yet been formally tallied. Aiken has a 369-vote lead, but "absentee ballots trickling in could change that," per the Washington Post.
