"So you have to represent a stream?"
To be a senator, yes. But congress is now full with the party you align with best.
"Maybe Pepe then, though that's gone dormant plus I'm not sure what the Pepe Party was exactly about, if they had specific stances. So I don't want to seem too phony..."

Article 6: Senate
Section 1: The Senate shall be formed of at least 15 members. Anyone is welcome to join the Senate if they so wish as long as they have their paperwork in order, have obtained a free voter ID from the Imgflip DMV, and have been elected or appointed by a stream to represent them. No government stream including IMGFLIP_PRESIDENTS, political party stream, or stream that provides a service to PRESIDENTS such as IMGFLIP_BANK or IMGFLIP_DMV may appoint a Senator.
