I've no doubt that UK politicians want nothing more than to emulate the US system of lobbying and campaign contributions.
Presidential elections are complete theatre now...it's very depressing but incredibly compelling. I've no doubt that the average UK backbencher pol could debate the pants off of any of the current republican presidential candidates. Each of them are seeming incapable of describing any issue with any substance whatsoever. That being said...the average backbencher would look awful on telly, doesn't own any guns, and doesn't pray to god for guidance.
The only good thing about the way things are going is that the republican party is self-destructing, but the trouble with that is we need a decent opposition to keep the democrats in check.
It always boils down to Americans get the government that they deserve. If people can't be arsed to get engaged then they deserve to get fecked over.
