The man convicted in the attack outside a supermarket that killed six people received a life prison sentence on Thursday.
And in a district across the state, Democrat Kyrsten Sinema is holding onto a 2,715-vote lead over Republican Vernon Parker while provisional and absentee votes are counted.
Parker might have Libertarian candidate Powell Gammill to blame if he does not win.
Gammill won more than 6% of the vote in Tuesday's election despite urging supporters to stay home rather than vote on Election Day in protest of the political system.
The unresolved contest in North Carolina could be the second tightest 2012 congressional race after provisional and absentee ballots are counted for the district that encompasses Wilmington and the area northwest to the Raleigh suburbs.
Democratic Rep. Mike McIntyre faced a tough re-election challenge. His district added Johnston County and his hometown of Lumberton was cut from the 7th District this year after redistricting.
Once the ballots are counted, either McIntyre or his Republican challenger and two-term state Sen. David Rouzer can request a recount if the margin remains a 1% or less. Both candidates have until November 20 to request a recount.
Gary Bartlett, the executive director for the State Board of Elections in North Carolina, said officials should know if Rouzer intends to request a recount before the November 20 deadline.
