As expected, the result from today’s elections in Colombia is a run-off next month.  What was not expected is that Santos came very close to winning outright in the first round and that he had roughly twice the votes of Mockus. 

From the National Registry:

Trying to find an additional 3.5% for Santos will be a lot easier than finding the 28.5% that Mockus needs.  There is also the question of who will turn out for the second round—and what the candidates do in terms of the campaign between now and then.
