The new Congress is pretty much the same as the old Congress when it comes to religion, and when it comes to gender. According to that last link at Vox:
The 115th Congress, which was officially sworn in on Tuesday, will be the most racially diverse Congress in history. Gender diversity, though, is another story.
While 14 non-incumbent women were elected to Congress in 2016, the overall number of women in Congress is staying exactly the same — 104, among both the House and Senate.
So how long, o Lord, how long?
