Unfortunately, I do not see these bigtime liberal ratholes performing a public function.
I wouldn’t call it a public function...I would analogize more to the public accommodation cases. Courts in the 50s and 60s held that Congress’ ability to force private businesses to not discriminate against customers was because racism affected public commerce and was against the public interest and constitutional principles. The same could be applied to monopolies that communicate political views across state lines. All Congress needs to do is pass a law requiring that such public outlets for expression be required to not discriminate against any legal form of opinion based on ideology.
