I am acutely aware that politicians toss the word “friend” far too loosely.

It’s abundantly true on Capitol Hill or perhaps in state capitols across the land, where politicians debate each other on the legislative floors, referring occasionally to their “friends on the other side of the aisle.”

Have you heard Senate Majority Leader Mitch McConnell and Minority Leader Harry Reid refer to each other as “my friend”? C’mon, dudes. Give me a break!

Well, the “friend” reference comes up now with Sen. John McCain backtracking on a statement about his former Senate “friend,” Barack H. Obama. He said that the president was “directly responsible” for the slaughter this past weekend in Orlando, Fla. He took that initial statement back — sort of — by saying it is the president’s decision to pull combat troops out of Iraq that gave rise to the Islamic State, to which the gunman reportedly pledged allegiance before opening fire in the nightclub.

I truly had thought in my heart of hearts that McCain and Obama actually were friends before they ended up running against each other for the presidency in 2008.

Do you remember the incident at a McCain town hall forum that year when an audience member questioned whether Sen. Obama was actually an “American,” and whether he was constitutionally qualified to run for president? McCain cut her off, defending his “friend” as a “fine American” and a “patriot”?

These “friendships” — if that’s what they are — seem so tenuous and fragile in the heat of political battle, which makes me wonder why these pols use the term so loosely in the first place.

You want transparency? Most of us can see right through such declarations of friendship.
