My thoughts on senator-cide will remain private, however, this game makes it look quite enjoyable and relaxing! Physics based puzzles are pretty fun in general so long as the physics are predictable and don't become a chaotic system quickly; this definitely passes the test. There's a lot of potential to be had with the mechanic, such as more moving parts, walls, bouncy stuff, etc - it would be a challenge of precision and timing. I like that you have a set amount of senators and the ratio of senators needed, since it prevents players from brute forcing through each puzzle, but allows enough for deliberate experimentation, and only a slim margin of execution error. This would probably have to vary per level and be balanced. Overall, interesting premise and great start to designing for the mechanic; definitely brimming with potential.
