He turned around the City, you must admit. Also, he DID do a good job during/after 9/11. The city needed a take charge personality, and he took charge. Call it superficial, but personality matters in moments like that, and in leading a war.
My main point, however, was that his abortion stand will prevent him from getting my primary vote.
The economy and specifically the stock market were on a roll during Rudy's term and this meant increased tax revenues for NYC. I haven't seen any indication that he cut spending, so the "turnaround" was more a result of increased revenues from economic growth. So, I don't see any reason to give Rudy credit for this, it was going to happen regardless.
Also, he DID do a good job during/after 9/11.
Rear Admiral Husband E. Kimmel did a good job in creating calm in the days after Pearl Harbor. He was subsequently fired and history shows that his failures paled in comparison to Rudy's. Rudy KNEW that the Twin Towers were a target and still decided to put the city's command center in an adjacent building. Rudy KNEW that evacuation would be critical if the Towers were ever attacked again, yet did nothing in over seven years to address this. There are many countries around the world were Rudy's "reward" for his actions surrounding 9/11 would have been a date with the executioner.
He ran NY like a mob boss, doing whatever he wanted and shunning those who didn't agree with him.
I don't trust his judgement.
