Democratic presidential contenders are already locked in an important battle to showcase their viability, racing to build digital armies to power their campaigns.
Online support is set to play a pivotal role in the Democratic primaries, after small-dollar donors using ActBlue, the Democratic online fundraising platform, financed the Democratic House takeover — and, before that, Sen. Bernie Sanders’ underdog 2016 presidential campaign. Potential candidates have spent months building up grassroots digital supporters to fund their campaigns in 2019 and build relationships with voters before they get the chance to go to the polls in 2020.
