Vote counts due after Clay Aiken primary opponent dies suddenly

Singer Clay Aiken's rival for the Democratic nomination for Congress, Keith Crisco, 71, died unexpectedly Monday, "after an accidental fall" at his home. The entertainer led Crisco by 369 votes for the Democratic nod in North Carolina's 2nd Congressional District, but the race was too close to call and not finalized. The counties in the district have until Tuesday to report their official canvass of votes. If Crisco does come back and win, local Democrats would select the nominee, an Aiken spokesperson said.

Lee, had joined the rebellion and desperate for more space to bury the accumulating dead of the Civil War, recommended that the Lee estate overlooking Washington be turned into a graveyard.

Posthumous Michael Jackson album 'Xscape' released

Even five years after his death, there is no escaping Michael Jackson. The latest evidence, Xscape, arrives Tuesday with eight "contemporized" castoffs the pop superstar recorded from 1983 to 1999. The project was hatched in September when Epic Records chief L.A. Reid met with Jackson estate co-executor John Branca. The estate combed Jackson's archives and found 24 suitable tracks.
