Sanders and his team have made clear their intention to tout the results of the first round of caucus voting Monday, even though the Iowa Democratic Party stresses that the only number that matters is the final delegate count.

Aides with two top-tier campaigns told POLITICO they worry the Sanders campaign or other pro-Sanders forces — which will be receiving unofficial precinct results from allies in real time — will disseminate that information through social media or publicly claim victory after the first vote, an act that could distort the eventual results in a variety of ways.

A claim of victory after the first vote could encourage supporters of weaker candidates to leave the caucuses early without realigning with another candidate. Or it could create an artificial bandwagon effect by encouraging some caucus-goers to jump to Sanders’ side under the belief that he will be the victor.
