Yep. Russia's largest federal subject (Yakutiya) is a third the size of the entire US, and it's one of 85 subjects)
Should have at least listed the Special Administrative Regions of China, Hong Kong and Macau which have their own passports and currencies. I'm not going to vote for China since I am not allowed to enter 95% of it without a visa.
... especially India
Both Russia and India are federal countries, just like USA, so might be a good idea.
But where to draw the line? Switzerland is also federation...
