This divergence of viewpoints - from doing nothing to appointing a special prosecutor - is putting President Obama in an uncomfortable position. ... But Obama appears reluctant to take any action that might further divide the country. Moreover, he may be loath to antagonize Republicans, whose support he may need on many other issues in the future.There is always a divergence of viewpoints. Justice should not have to depend on consensus. Nevertheless, you say yourself that "a sizable majority of Americans favor an investigation into Bush-era misconduct."
Investigations and prosecutions are never pleasant. There will never be a convenient time. "Further divide the country?" It was the Bushies who were deliberately divisive. The November election and popular support for Obama since then shows that we are currently less divided than we have been for a long time.
Obama is in quite a lot of uncomfortable positions. That's what he signed up for.
Republicans have just as many reasons, if not more, to want an investigation into Bush-era misconduct. Weren't they doing everything they could to put distance between themselves and Bush during the election? And isn't it the fault of the Bushies that the Republicans performed so abysmally in the election?
The bottom line is that if we don't investigate and prosecute Bush-era crimes, we set ourselves up for more of the same in the future. There will be absolutely nothing to prevent future leaders from doing the same unless we go forward with the investigations.
