World Trade Center garage bombing by Al Qaeda: 37 days after Bubba took office.
9/11: 8 months, 22 days, after W was sworn in.
The true gaffe would be if candidates weren't thinking that. It's just that reality these days is oftentimes far too scary for the masses, or the MSM, to digest.
"Those who cannot learn from history are doomed to repeat it."
