The Democratic Iowa Caucuses are a bit bizarre. The % figures are 49.9% for Clinton and 49.6% for Sanders. But those percentages relate to delegates and not votes. The DNC won't release the voting tallies. Candidates are required to poll at least 15% of the statewide vote to get any statewide delegates and at least 15% of the vote in any congressional district to get delegates in that district. O'Malley looks as though he got 1% or less of the vote, but in fact he may have had 5-15% of the vote. How his supporters spill to the other 2 candidates may be important in the remaining primaries.
The other thing is that delegates are awarded proportionally so that Clinton and Sanders will end up with almost the same number of delegates in Iowa.
