It’s just my opinion based on 45+ years of observation and living. I have no idea what others have as positions. from what I can tell, the current fed Gov, is doing nothing.
I also don’t believe that widely used substances or contraband in this case, is a federalism matter. This is why we have federal law enforcement.
What Colorado is doing, and California has done is to challenge that long held institution because it can. because Obama is not engaged in it.
If you want that to continue, then vote democrat. Because they use that constituency to win elections, they buy it off with a unofficial wink and nod.
That has never been the case in a republican admin but there is always a first time. I think the country is on it’s last legs anyway.
Have you anything to say about the 10th Amendment?
