I know it is election season, and being a foreigner I try to stay out of it although the election of the US President means a lot to the part of the world we still call the Free World.
However, let us not rewrite history completely. Remember Clinton did not take out Osama when he could have done so? Remember Gorelick and the stove-piping of intelligence? Remember the Florida fiasco (more Gore than Clinton, but definitely the Dem party), which caused all Bush's nominations tot be delayed?
All points that were discussed thouroughly here at FR those many years ago.
You are right, however...
Nobody can remember Gorelick these days, but the calendar is easy to read. Bush elected in November, 10 months later 9/11 happened. Easy math, and the Democrats are always reminded us it was Bush's fault, not Bill Clinton's.
Except for a few people who studied 2011 events and remember them, it was on GWB's watch and that is where it will stick. Trump knows that and so does Jeb.
