The actual cap is 54k per seat, so it can scale. You can bring that number up or down as needed to adjust for the seat representation size in the US, but it is significantly below, say, Hakeem Jeffries raising $17M and Mike Johnson $13M. The other bit is that the Parliament has more constituencies than the US House despite the House representing more people, so the number of people per House member is quite high. And that's not actually specified in the Constitution but a law that could be changed by Congress at any time. https://en.wikipedia.org/wiki/Reapportionment_Act_of_1929 https://en.wikipedia.org/wiki/Reapportionment_Act_of_1929
