It may seem strange that the major US TV networks have now all projected that President Obama has won re-election despite the fact that his challengers still is over one million votes ahead in the popular vote. As you certainly know if you have been following the coverage here, it is that state-by-state electoral vote that determines who wins and, according to projections, Mr Obama now has at least 274 electoral votes, four more than the minimum needed. As for the popular vote, Mr Romney's margin will likely shrink and possibly disappear as votes from big states like California come in.
