Hillary Clinton’s lack of appeal with young voters is quickly emerging as her Achilles heel and a look at each of the candidate’s popularity on Facebook provides further evidence. Barack Obama has attracted almost 200,000 supporters compared to just 60,000 for Clinton. Last night saw the first of the ABC/Facebook debates and the accompanying US Politics Group - from where the chart below is taken - is well worth a look. The most striking feature for me is the contrast in Facebook support between the Democrats and Republicans overall. There are no shortage of young Republicans on Facebook but it appears the GOP candidates either don’t know how to attract them or bizarrely, simply don’t care.
