This system of voting for parties might sound strange, but it actually has a number of advantages over simple winner-take-all voting. It prevents gerrymandering... it promotes third parties... and leads to stronger political parties
Those districts are too big. During the ratification debates, some people actually argued that the House districts were too large given the power the federal government would have. I shudder at what they would say about districts 35 times bigger, especially when the number of representatives hasn’t changed in over a century.
You don’t have a civic responsibility to vote. You have a civic responsibility to be an informed voter.
