Illegal immigration??? (crickets chirping...)
Giuliani is a law and order fanatic. Obsessive almost.
As Mayor of a huge city he had to act in a certain way to keep law and order in his city(and that included not doing the job of the Federal Government) but if border security is his responsibility as President, I don't believe any candidate, any, would be tougher.
I will make anyone a bet that if Giuliani is President at one time or another he will be called a Fascist by the MSM for his border policies- as Conservative cheer.
