Facebook, Twitter and Instagram have been greatest used in Obama's presidential election. Good news is Obama team is still looking computing experts, mathematicians, programmers and statisticians.

The team's new chief scientist is Rayid Ghani said that the challenge was to make best use of the vast amounts of data available to campaigns on the actions, behaviour and preferences of voters. These days electoral rolls have been linked with commercially available consumer data, and names and addresses of voters are cross referenced with everything from magazine subscriptions and home ownership, to hunting licenses and credit scores.

Wishful thought that American have president election every year, so can create more I.T. jobs in U.S.
