A quick reminder of what a failure George W. Bush was

-It's true that he was warned about 9/11, and failed to stop it, proof

-DID NOT unite the country after 9/11, that, in fact, was a result of Al Gore calling on his party to unite behind Bush.   Al Gore is crazy, boring, and not pragmatic, but he did play a great role in uniting us after 9/11, Bush did not.

-The Iraq war.

-Gas prices rose exponentially, OPEC held us hostage, failed to take action, gas went up past $4.00 per gallon. proof

-Killed the economy in 2008, exact cause is still being debated.

-Turned Bill Clinton's surplus into a deficit, and is friends with Barack Obama, who made that problem worse.

So yeah, Trump was right to call GWB a failure at the GOP Debate.
