MICHAEL WALSH: Benghazi Blues. “No matter what happens with Darrell Issa’s congressional committee meetings this week, we are witnessing the beginning of the end of the Obama Administration, and the cause is Benghazi. It’s impossible to underestimate the blowback that has been gathering steam for the past seven months, now about to erupt with full force. Few reputations will emerge unscathed, Obama’s presidency will be crippled, Hillary Clinton’s 2016 candidacy will be destroyed — and perhaps some new heroes will be born.”
