Question

How does federalism limit national power?

Answer 1

Well it makes it seem less of a 'dictatorship.' If it weren't for the Federal Laws, the present has all power and control over the nation. With that being said, consuls and senators help with discussions. Making laws and legislation.

I hoped I helped :)

Answer 2

The answer i am positive your looking for is "It creates two sovereigns, the national government and the state governments."
