Could be Katrina, it seems to me the light wasn't seen by the non leftists until after Katrina despite the way being botched pretty much from day 1...he got re-elected for goodness sake! Despite Democratic approval pretty much mirroring or possibly even worse than Obama's numbers among the GOP.
I still voted for the Iraq War,but it's certainly not the only reason.
True, Katrina was where on the most partisan Republican hacks could defend Bush. I had read years before that NOLA was highly vulnerable to a hurricane. There was an earlier hurricane that I remember thankfully missing NOLA. I remember reading one Friday that Katrina was a very strong (Cat 5?) hurricane and its path would hit NOLA in 3 days. It was obvious that it going to be a huge disaster. What did Bush do? The same thing he did for 9/11, ignore the issue. He decided to celebrate McCain's birthday instead. No one could have predicted that Bush would lie about no one predicting the levees failing.
