The sources are a bit biased, but if it's true maybe this will tarnish the untouchable aura of "America's Mayor".

He ran a CITY, it was just a city, not a state, not a county even, and certainly not a country, every time he says "I ran the best government ever" I want to scream! He cheats on his wives, has stated that he's not really a republican, and has sued the country over illegal aliens rights, yet now he says he would be the toughest on illegal immigration and borders! Please some one tell me how this man is the frontrunner? Anybody? (okay, I am done, my apologies for this little rant)

He's the front runner for one reason, and one reason only. People have a glorified image of him walking amongst rubble on September 11, 2001 and "leading" NYC through that catastrophe.
