I think Glen gets it right when he describes that port controversy as much ado about nothing. At the same time, Constant (via Cut to the Chase) may be on to something when she suggests that this whole "controversy" might be nothing more than ruse to give the Republicans a chance to "look tough" against the president while ignoring the NSA domestic spying controversy. On her blog, Constant provides some suggestions on what we need to do to address the illegal spying on Americans.
P.S. WaPo has a good sensible article on the whole ports issue.
