In my opinion it is still a significant and real criticism about Obama. Definitely fair game when vetting for the #1 position in the land. Obama's historical connections to several left wingers is at very least concerning.
However, I agree...everything pales in comparison to the economic crisis. unfortunately, economics is not a strong suit for either of the candidates. Government's interference in directing loans is part of the reason we are in this mess. The greedy bankers are also to blame, and so are individuals who overreahced & should have known better...but no one will learn from their mistakes because our government bails them out.
