No, he does not measure up. But then, who does? Reagan had a great [and potentially very dangerous] gift of charismatic leadership. Luckily for mankind, this gift is rare, for the likes of Reagan make maybe 5% of its possessors, while the likes of Hitler - at least 50%.
This is exactly why I oppose Giuliani. I believe he does have the gift of charismatic leadership. How many people support him even though he opposes most of their beliefs, doesn't actually have a great record on terrorism, etc.? He's obviously not Reagan or Hitler -- but his record shows clearly that he recognizes no lawful, Constitutional contraints on his actions when he's in power. That disregard, combined with charismatic leadership, makes him a very poor choice for the presidency.
