As Americans we like to see things in Black and White (no pun intended here), where gray is the color of compromise and the color of politics. It's unfortunate to see the contest for the Presidency swirl around the ranting of a retired pastor who clearly does not speak for Obama.
Although Reverend Wright's naive and misguided liberation theology themes are a legitimate issue, they should not be considered a major issue. Why? Because Obama's record is clear on many topics already, and he's not getting elected to be the national pastor. It's very reasonable to take Obama to task regarding his long term relationship with a person who holds the US Government in such great contempt, but it's not reasonable to reject Obama's answers out of hand.
The story is a perfect storm of fodder for right wingers like Sean Hannity, who is always on a crusade to cut down moderates and left-wing politicians like Obama. More than anybody Hannity has massaged this minor issue into a major one. One can only wonder if Hannity would even *pay attention* if the issue were racist rantings of white pastors. I don't think Hannity is a racist, but I believe he's hyping this issue beyond reasonable measure to further the Republican political agenda.
It's working.
