John Hills, a law professor at Indiana University and author of "The Political Centrist," says tough political exchanges are endemic to the American political system. Others say putting crosshairs on representatives in Congress like Giffords on websites or its equivalent wasn't the practice since the times of Jefferson and Adams. We looked at the letters of George Washington during the long struggle with the British and it showed composure and civility even in dire circumstances and difficulties. Criticism by Washington of the lack of help and risks he was exposed to throughout the war was worded carefully, with civility and yet conveys the great urgency. What about the letters of Jefferson and Adams who were on opposite sides of the debates of that time, a time more infused with momentous issues because of the French revolutionary tide in those years? A letter to Abigail Adams, from Washington, June 13, 1804, gives a glimpse of that relationship: "The friendship with which you honored me has ever been valued, and fully reciprocated, and altho' events have been passing which may be trying to some minds, I never believed yours to be of that kind, nor felt that my own was. Neither my estimate of your character, nor the esteem founded on that, have ever been lessened for a single moment, although doubts whether it would be acceptable may have forbidden manifestations of it. Mr Adams friendship and mine began at an earlier date. It accompanied us thro' long and important scenes. The different conclusions that we had drawn from our political reading and reflections were not permitted to lessen mutual esteem, each party being conscious they were the result of an honest conviction in the other. Like differences of opinion existing among our fellow citizens attached them to the one or the other of us, and produced a rivalship in their minds which did not exist in ours." Jefferson in this letter says that one act of Adam's gave him a moment of personal displeasure, the last appointments by Adams as President "from among my most ardent political enemies." This says Jefferson "laid me under the embarrassment of acting thro' men whose views were to defeat mine, or to encounter the odium of putting others in their places...If my respect for him did not permit me to ascribe the whole blame on the influence of others, it left something for friendship to forgive, and after brooding over it for some little time, and not alwasys resisting the expression of it, I forgave it cordially, and returned to the same state of esteem and respect for him which had long subsisted...I maintain for him and shall carry into private life an unform and high measure of respect and goodwill, and for yourself a sincere attachment."...
