That's not really an excuse for the error. The general term for the thing in question is a legislature (which is also California's specific term.) Being wrong and calling it California's Congress doesn't make it more accessible, nor does calling state legislators "Congress members"just, it just makes it look like you don't know what you are talking about to anyone with even a passing familiarity with California government.
And if you can't get that kind of basic thing right, why would people trust you on the substance, which takes a lot more understanding of government to interpret correctly.
