Since 18-24 year olds already ignore their ability to vote there is no reason to expect that 16-18 year olds will be any more interested. At the moment over 50% of 18-24 year olds don’t vote even though they are eligible. [1] So this kind of change is hardly going to offset aging. It is also wrong to suggest that voters vote according to their age; the elderly are likely to have grandchildren whose interests they may well respect when voting.
