Question

How have the day-to-day workings of government affected how we interpret the constitution?

Answer 1

I believe the answer is: the Supreme Court makes key rulings on constitutional issues

These key rulings often time referred to as landmark decision that lead to the amendment of the constitution. Example of this would be the 19th amendment of the constitution, which granted the men with the right to vote (on early draft, it is specifically stated that all men had the right to vote)
