Rev. Wright's Comment at his Rochester Stop

I have heard many in the media point to Obama’s dropping poll numbers as a sign of the "racism" that "still haunts our society."   From City Newspaper's article about the Rev. Jeremiah Wright's visit to Rochester:

Wright’s sermon was followed by a brief question-and-answer period with the Rev. Rickey B. Harvey, Mt. Olivet’s pastor. Harvey asked why Obama’s poll numbers are sagging, and the previously loquacious Wright gave a short, measured answer.

“We are not in post-racial America,” he said.

So let me try and understand this concept.   People weren’t racist enough to stop them voting for a black man for president, but after they did, their racism “kicked in” and now they hate blacks which is reflected in the President’s poll numbers?   This is absurd.
