My friends and acquaintances on the right are fond these days of reminding me of something I knew already.

It is that U.S. Sens. Barack Obama and Hillary Rodham Clinton said angry things to and about each other when they ran for the Democratic Party’s presidential nomination in 2008.

Then Sen. Obama was nominated. He went on to be elected president. Then he hired Sen. Clinton to be secretary of state in the first Obama administration.

All was “forgiven,” more or less. The rivals became allies. Then they became friends … or so they said.

The pushback on this issue comes from those on my right and far right who keep yapping at my continuing observation about Donald J. Trump’s former foes/enemies are now lining up for spots in the president-elect’s Cabinet.

Mitt Romney is being considered for secretary of state; Mitt called Trump a “phony” and a “fraud.”

Rick Perry is being considered either for secretary of defense or energy; the former Texas governor called Trump a “cancer on conservatism.”

Chris Christie once led the Trump transition, then he got pushed aside and now he’s back in Trump’s semi-good graces; Christie once said Trump was “unfit” to be president.

The list of “establishment Republicans” who have condemned Trump is long and distinguished. Here they are, though, lining up behind the new president.

Sure thing. Democrats do the very same thing. John F. Kennedy and Lyndon Johnson weren’t exactly BFFs when they ran against each other in 1960; then JFK picked LBJ to run with him on the winning ticket.

I guess one’s reaction to this kind of political mood swing depends on your own point of view.

Therefore, I won’t apologize for overlooking how Democrats have played this very same game … at least not until my Republican friends acknowledge publicly what’s occurring at this moment in history with their guy and his former foes.
