When an election is very close, there's an automatic recount, paid
for by the government. In Colorado, the margin is 1/2 of 1% of the
highest vote total in the contest. If Candidate A got 1,000 votes, and
candidate B got 990, there would be no automatic recount because the
difference of 10 votes is more than 1/2 of 1% of A's 1000 -- 5 votes in
this example. A candidate can, however, get a recount at his own
expense, no matter what the margin.
