Lawmakers abiding by the platform would have also opposed the Cyber Intelligence Sharing and Protection Act (CISPA), a bill that would allow private companies to share a broad range of information about their customers with U.S. agencies in an effort to fight cyberthreats, he said.

"It's important for politicians to know that if they act contrary to these Internet freedom principles, they'll risk the wrath of their party's most committed activists," Segal said in a statement. "It is clear today that censoring the internet or monitoring internet users is wildly unpopular, and we urge Democrats to join the fight to protect the Internet today by forming their own party platform plank."

The Republican Platform also rips President Barack Obama's administration for being "frozen in the past" on Internet and communications policy. The Obama administration has conducted no wireless spectrum auctions, has not given carriers any incentives for investment and has embraced the U.S. Federal Communication Commission's net neutrality rule, which tries to "micromanage telecom as if it were a railroad network," the platform says.

The Obama administration has made "no progress" toward its goal of universal broadband coverage, the platform adds.

The platform also calls for the prohibition of gambling over the Internet and calls on the government to "vigorously" enforce all current laws against pornography and obscenity online.
