Bush was on vacation clearing brush 1/2 of his presidency until 9/11, and as we found out later, he'd been gunning for invading Iraq since he became President. Plus, Bush flatly ignored the report that Bin Laden was going to attack the US.
There's no fucking way that Al Gore would have sent our military to invade Iraq, pushed for torture, greatly expanded the secret prisons. That war drained our military, drained our economy, and filled our hospitals with vetrans who will be on healthcare for the rest of their lives.
Al Gore's big thing was fighting climate change, which would have resulted in a new technology and research boom in America, NO NEW WARS, and he would not have pissed away the goodwill of the foreign nations, if he'd been unable to prevent 9/11. Plus, fighting climate change has the side-effect of reducing our foreign energy dependence. I have no doubt that Al Gore would have had a better pick for FEMA head, and a better response for Katrina. He wouldn't have been the second coming of Christ, but at least he wouldn't have been indifferent and snarky and intentionally destroying government effectiveness.
Bush and his team were fucking awful for the US.
Obama's pretty fucking decent. He can actually write his own speeches, and he reads the newspapers, and he can effectively lead and organize. That'll be a shit-load better than Bush. If people are treating Obama like the second-coming, it's only because we've survived eight-years of Bush.
