I have posted many times to explain the "WHY" of the situation.

Go to Google and read a dozen articles about the USA and 'States Rights' and why it is so difficult to change!
There is simply **NO** simple path for national referendums on things like alcohol, abortion, immigration, marriage laws... and gun laws.

We are a different country than you, with a different history and different rules. It all made sense in 1780, when we were just a group of semi-isolated colonies, and when we decided to organize as a **country**, those colonies became *states* and were soon divided about things like slavery. Then, as we gradually moved West..(paying little attention to the rights of the indigenous people)... new states-still days or weeks of travel from Washington D.C., wanted to make their state in their own mold.

Now, it takes a Constitutional Amendment to change and of that basic setup....and requires years and "The amendment must then be ratified by three-fourths of the State legislatures, or three-fourths of conventions called in each State for ratification." And those 'conservative' states DO NOT WISH to change and be ruled by a central government!!

The USA is not Britain... we don't even know how to be any longer.
