Maybe when Graham was just elected, McCain was the one who helped him get on the Senate Committees he wanted to be on (both served in Military) and maybe that military background sort of resulted in a sense of loyalty to “a superior officer so to speak” and Graham never went against McCain on key issues. Now that Senator McCain has passed on, Graham has no more loyalty to anyone and is taking positions that he and what his South Carolina constituents think are best. Maybe?
Good point and quite plausible. I guess time will tell.
