Voters have faxed 800,000 pages of political opinions to their elected officials using Resistbot

As voters scrambled for new ways to raise their voices after Election Day, two Silicon Valley engineers introduced Resistbot — a tool that turns voters’ text messages into notes faxed directly to their members of Congress.

In the weeks after its March launch, Resistbot has spiked in popularity: Voters have sent roughly 800,000 pages’ worth of political opinions to their elected officials. And the flood of activity has come as its creators embark on an expansion, far beyond faxes to Capitol Hill. Beginning in April, Resistbot users can share their views about health care, immigration, taxes or anything else not just with congressional lawmakers but also state governors and local newspapers, according to one of its founders, Jason Putorti, who spoke with Recode this week.
