isn't this a Brexit thread, if you guys want to argue with Pelosi, there are plenty of threads to do that (I say this, as an American who did not care for her 60 Minutes appearance)
EDIT: there are also structural and cultural differences with American and the UK that make these comparisons very tough, but having followed both UK and US politics fairly closely, it's really hard to compare them in a clean, 1-to-1 manner. Maybe, probably, most elected Democrats would be Labour politicians if they had come up through the UK political system, some might be LibDems, but even that is tough to game out because when you come up in politics largely defines your world view of what is possible. I find this whole discussion to always be rather silly.
