A big thing that bothers me about US elections is that around 57% of the vote went for the Democrats and around 41% went towards the Republicans. It's a YUDGE difference. Yet, the Republicans gained 2 Senators (as of today). As an outsider, it seems as if the US is not a democracy at all.
No, not really. It comes from two senators from North Dakota representing around 670 000 thousand people having the same vote as the two senators from California with a population of around 40 million.
