The editors of the National Review weigh in on the Rudy for President quasi-bandwagon, largely from a pro-life/pro-choice perspective:
But there are serious obstacles to Giuliani’s winning the embrace of conservatives. Putting aside his tumultuous personal life, his positions on many national issues, from tax reform to the environment, are largely unknown and will be more closely examined. On social issues, however, his liberal views are well known and so present a threshold question for many conservatives. Giuliani’s most important flaw in this regard is his denial that unborn children have a right to life.
Unfortunately, they don't even mention another major flaw: his support for illegal immigration.
