So, for Congress, 3 members at a max for each party will be selected but it can be less depending on which independents you want in Congress. As for who can pick how many, since the introduction of the HoS, here are the amount of members you can pick.
President: 3
Vice President: 3
Head of Congress: 3
Head of Senate: 2*
Automatic Picks: 4*
*the 4 automatic picks are the runners up in the Presidental, Congressional and Senational election, leaving the person with the least power (Head of Senate) to get only 2 picks.
As for the Senate, we will get representatives from other streams that are active in Imgflip Presidents to represent a stream and vote on Congressional proposals. You cannot be a MoC and a MoS at the same time. Cabinet Members are allowed in the Senate, but have to resign if they step in for someone. As for who can pick how many, the Senate consists of 10 members so here’s how it will work.
President: 3
Vice President: 2
Head of Congress: 2
Head of Senate: 3
