Paul Krugman remearks:

"Mr. Bush got us into the Iraq quagmire by conflating Saddam with Al Qaeda, treating two mutually hostile groups as if they constituted a single enemy. Well, Mr. Romney offers more of that. "There is a global jihadist effort," he warned in the second debate. "And they've come together as Shia and Sunni and Hezbollah and Hamas and the Muslim Brotherhood and Al Qaeda with that intent." Aren't Sunnis and Shiites killing each other, not coming together? Nevermind.

What about the administration's state of denial over Iraq, its unwillingness to face up to reality? None of the leading G.O.P. presidential contenders seem any different — certainly not Mr. McCain, who strolled through a Baghdad marketplace wearing a bulletproof vest, accompanied by more than 100 soldiers in armored Humvees while attack helicopters flew overhead, then declared that his experience proved there are parts of Baghdad where you can "walk freely."

Finally, what about the Bush administration's trademark incompetence? In appointing unqualified loyalists to key positions, Mr. Bush was just following the advice of the Heritage Foundation, which urged him back in 2001 to "make appointment decisions based on loyalty first and expertise second." And the base doesn't mind: the Bernie Kerik affair — Mr. Giuliani's attempt to get his corrupt, possibly mob-connected business partner appointed to head the department of homeland security — hasn't kept Mr. Giuliani from becoming the apparent front-runner for the Republican nomination.

What we need to realize is that the infamous "Bush bubble," the administration's no-reality zone, extends a long way beyond the White House. Millions of Americans believe that patriotic torturers are keeping us safe, that there's a vast Islamic axis of evil, that victory in Iraq is just around the corner, that Bush appointees are doing a heckuva job — and that news reports contradicting these beliefs reflect liberal media bias."
