I don't like the idea of giving out "credentials", because the government machine can then (continue to) pick and choose who the messengers are and it's basically propaganda. Here's my idea for an alternative: The two leading parties maybe could each pick 2 outlets to allow in, then We the People could vote in 10 others to have regular seats, and finally, questions from the general public could be collected on an open source or blockchain system that randomly picks 50 questions. Citizens then can upvote and downvote those 50 questions and the press secretary must directly address the top 5. Just my 2¢.
