It is the sort of thing you hear from Peggy Noonan and her path-finder / mentor David Gergen who advises Trump to forgive and forget about the Swamp’s attempt to destroy him and his voters. In Gergen’s use it is dressed up as a Churchillian virtue, — as in let Democrats off the hook so that they can regroup and do it again. We see a lot of politicians, Democrats and Republicans, and media personalities with the paddles and the enthusiasm for membership in the unity party — AKA the Swamp. For them it is everything. Not so Trump.
