I think Duncan can go all the way. He has the time to gather the right team before the primaries. He's real and he's running against phonies -- that wins elections. His policies are on target with middle america, and his strong stance & military bearing are the types of things average voters appreciate in a president.
Duncan ran a $530BILLION budget, much bigger than anything Rudy ran as a mayor. He has been rubbing elbows with some big money people that make some of the others in the race look cheap in comparison, and he has grassroots support along the same par as Dean.
The more you get to know him, the more you like what you see; it's just the opposite with Rudy.
I hope your right. In the meantime, up until the primaries themselves (and hopefully afterwards), I'll continue to be a staunch Duncan supporter.
