What evidence do you have for this? Let's not forget that Rudy was mayor of NYC for seven and a half years before 9/11. He knew that the WTC was a target after the 1993 bombing and he also knew from that episode that the biggest problem with the WTC would be evacuation. And he made no effort to develop an evacuation plan.
If it’s a choice between Rudy and any of the current crop of Dems in the general election, I know that the Dems cannot continue the fight against Islamofascism. I believe Rudy can based upon his continued support for the wars in Afghanistan and Iraq and his multiple comments regarding Iran, Syria, Hamas, Hezbollah, etc.
Is he the BEST choice? IMHO, no.
Of course, this is all hypothetical at this stage anyways. ;-)
