You do not even know what gerrymandering is, how it works, or what its effects and limitations are. This is a uniquely-American issue, and not one hat even an intelligent Brit would have any chance of properly understanding, much less a bottom-of-the-line Welsh ignoramus such as yourself.
Much more so even than in most cases where you ignorantly stick your nose in America's business where it has no legitimate cause to be, and presume to tell us how to run our country (even though, by your own repeated admission, you British cannot even govern your own country); her you are showing the world just how extreme your ignorance is.
Worry about the degenerate, ungovernable shithole in which you live, and just keep your filthy British nose out of America's business.
