This is why it’s a donation to the party - not to them or their office - although they can want a campaign contribution, which again doesn’t count as going to them.

I’ve had an MP literally solicit this from me - he emailed a bunch of local businesses basically stating his price list. He’s no longer an MP, or in politics - but you see this stuff everywhere, all the time. Any member’s bill you see has almost certainly been sponsored.

MPs typically move in packs ("areas" or "currents", that may or may not be officially organized around a thinktank or club), so buying the right MP you can actually move several of them. And then your representative goes and trades favors with the colleagues in government - "I'll vote for your controversial legislation if you pull that other lever over there". Representative democracy is a big sausage factory: in go blood and guts, out comes "edible" rules that society will live on.

It doesn't though, that's my point. The Isle of Man has MHKs and ministers, not "MPs": https://en.wikipedia.org/wiki/House_of_Keys.

It's like saying a politician in the UK is a "senator" and expecting people think you are an authority on the subject.
