US mid-terms 2014: Is West Virginia on the right track?

Americans are voting in mid-term elections which will decide who controls the Senate and pave the way for the 2016 race for the White House.

Polling booths opened in the eastern states at 06:00 local time (11:00 GMT).

The Republicans, who already control the House of Representatives, need to gain just six seats to take the Senate.

Rajini Vaidyanathan reports from one of the key battleground states, West Virginia, which may be about to elect its first Republican Senator for half a century.
