But now that we've been the United States of America for a while and none of the states seem likely to secede, the fact that California has 69 times more people than Wyoming but the same representation in the Senate is an offensive anachronism, at least to Californians.
What a dick. If California doesn't like it, all they need is to get 2/3 of the states and then the voters of those states to agree with them. Or something like that. Until then, tough shit.
An anachronism is something that belongs to an earlier time. "2 senators per state" belongs in this time, by definition, unless the constitution is amended. That's how it works. Period.
