Sanders campaign requests Kentucky vote recanvass

The Sanders campaign said it has asked the Kentucky secretary of state to have election officials review electronic voting machines and absentee ballots from last week's primary in each of the state's 120 counties.

Sanders has vowed to amass as many delegates as possible in his lengthy primary fight against Clinton, where he trails the former secretary of state by 271 pledged delegates according to a count by The Associated Press.

Clinton holds a substantial lead with party leaders and elected officials, called superdelegates, and is on track to clinch the nomination through the combination of pledged delegates and superdelegates after contests on June 7.

The delegate will be awarded based on final vote tallies and Clinton currently leads Sanders by a slim margin of about 500 votes in that district.
