Groups of Hillary Clinton and Bernie Sanders supporters are telling Iowa caucusgoers the best thing they can do for their favorite candidate may actually be voting for Martin O'Malley. (Video via Martin O'Malley for President)
Voting in the Iowa caucuses is a bit complex. Put simply, if losing a precinct seems likely, it can be better to take delegates from your rival than to try to win them yourself.

That's because any candidate who passes a certain threshold, usually around around 15 percent of a precinct's vote, in the first round of the caucus is eligible to win the votes of those whose candidate didn't pass that mark.

Getting O'Malley to 15 percent in the first round could guarantee he'll take a delegate away from the precinct's leader, and then he has the chance to win more delegates in the second round. (Video via Martin O'Malley for President)
The latest RealClearPolitics average has O'Malley holding 4 percent of Iowa's democratic vote.
