For the first time this year, Microsoft partnered with the Iowa Democratic and Republican Parties to provide a technology platform with which the parties will run their caucuses. The software giant created separate mobile apps for each party, which officials at hundreds of caucuses across the state will use to report out results from individual precincts to party headquarters for tabulation.

The arrangement has aroused the suspicions of aides to Sanders, who regularly warn that corporate power and the billionaire class are trying to hijack democracy. Pete D'Alessandro, who is running the Iowa portion of Sanders' campaign, questioned the motives of the major multinational corporation in an interview with MSNBC: "You'd have to ask yourself why they'd want to give something like that away for free."
