You might Google "9/11 Republicans" From Ann Althouse, quoting Ron Silver's daughter:
[H]e is still a registered Democrat, and Mr. Silver told his convention audience that he has not disavowed the left's social agenda. But at the moment he represents a particular slice of the American political spectrum: voters who put national security before ideology and want to keep President Bush's hand on the nation's rudder.
"I'm a 9/11 Republican," he said. "If we don't get this right, all the other things don't matter worth a hill of beans. I'll live to fight another day on health care, environmental concerns and sensible gun legislation. But this is such a predominant issue that it towers above all others, and I'm not certain both parties are capable of handling it the right way."

I think you're right. It may have been 9/11 Republican not 9/12. Oops. Will follow up...
