You’d think Roosevelt had passed away or some such thing.
I thought similarly.
Since when does a Senator warrant having flags flown at half mast until his funeral?
The Code says for a day and a half.
Not "as long as we are driving his corpse across the country so that a grieving Nation can pay their respects"
McCain was NOT Abe Lincoln.
I doubt that many people will be gathering along I-70 to pay tribute.
