I remember the generosity of Reagan in allowing Carter to be on the plane to meet the hostages and greet them.
Contrast with the “we won” “republicans need to sit in the back of the bus” hostility bristling from Obama.
I despised the man then because it was thanks to his cheerleading for the enemy that a lot of good men never made it home from Vietnam, but I despised him even more then. "Why", I thought, "should a president get credit for cleaning up a mess he made?"
But Reagan, in his greater wisdom, realized 40% or so of the country had voted for Carter and it was part of his job to unite the country. So what if Carter had another moment in the sun?
Compare and contrast that attitude to BO and how he treated Bush, McCain and Romney, who had won a far greater share of the vote.
