UK lowers voting age to 16

Britain's government says if 16- and 17-year-olds are mature enough to work and pay taxes, they're old enough to vote. So, the UK is lowering its voting age to 16 in time for the next general election. Other countries that have made the move haven't seen dramatic changes in voting patterns. The University of Edinburgh's Jan Eichhorn has looked at global trends and discusses his findings with The World's Host Marco Werman.
