WASHINGTON (AP) — The last undecided House race has been called for the incumbent Democrat, bringing an unofficial close to the 2012 campaign more than three weeks after Election Day.

North Carolina Rep. Mike McIntyre will return to Congress in 2013 after barely surviving a challenge from David Rouzer. The Republican conceded to McIntyre on Wednesday night after a recount showed the Democrat maintaining a small lead.

With McIntyre's race decided, only two House seats in next year's Congress remain up for grabs. Rep. Jesse Jackson Jr., an Illinois Democrat, won re-election but resigned last week, citing ongoing health issues and acknowledging he's the subject of a federal investigation. Special primary elections to nominate candidates to replace him will be held in February.
