Dear President Obama,
First the why: Once in office, you grew weaker because you detached yourself from the forces that swept you into the White House.
It was a moral and spiritual force that lifted you to the presidency, a force expressed by the yearnings of millions for America to rise from the darkness into which your predecessor had led us.
The unprecedented nature of your election - a relatively inexperienced black man reaching the highest office in the land - was possible only because of the unprecedented nature of the moral and spiritual damage the Bush presidency had inflicted upon the nation (with its reign of lies, fomenting of division, waging of unnecessary war, and usurpatious trampling on the Constitution and the rule of law) and because of the sense of purity and elevation you conveyed in your campaign.
You are smaller now, and this diminution was not inevitable.
You were brought to power as the champion of light over darkness, and you squandered it by neglecting that role. In this, there have been three main errors.
First, you spoke to us mainly as a policy wonk and did little to connect your plans with our moral and spiritual yearnings.
Second, and more important, you too readily muddied the moral waters, blurring the battle lines. Perhaps underestimating the strength available to you from a course of greater boldness and moral clarity, you were over-eager to make bargains - often bad ones, at that - with the forces you had been elected to combat.
To name one area of such muddying: Political reality may have dictated "looking forward and not backward" when it came to prosecuting or even investigating the previous administration's crimes - though they're crimes of the kind about which our Founders worried most. But why send your own Justice Department into court to defend the indefensible?
(Like, most recently, arguing for the immunity of those in George W. Bush's Department of Justice who wrote memos in apparent bad faith to declare legal what were crimes: If the memos' writers are immune because they simply gave opinions, and if everyone who follows those opinions is immunized by the memos, then all future presidents have a blueprint for committing any crime they choose.)
That your opposition is animated by that same dark spirit is shown in their making a divisive war of nearly every issue; in their continuous propagating of fear-mongering lies; and, above all, in their overriding commitment, even at a time of multiple national crises, to making you fail, simply so they can regain power.
But, except for rare instances, you've ignored how extreme and destructive is your opposition's behavior by the lights of American ideals and the standards of American history.
