NBC "News" obsessed with Hurricane Katrina

NBC Nightly News last night continued the whining about Bush and Hurricane Katrina in 2005.

"The Superdome, a symbol of official failure seven years ago..."

And of course Katrina is a pall over the GOP convention according to NBC.

Could they possibly be any more biased? Could they possibly be any more shamelessly political? Come on, NBC, can you at least pretend to be delivering the news instead of Barack Obama's talking points?
