Halperin's 15 things that McCain underestimates

Mark Halperin has put up his list of 15 things that John McCain underestimates about Obama and the upcoming contest.

Among my favorites on his list:

1. The astonishing enthusiasm that Obama inspires in his supporters -- and how much it contrasts with the respect, but not passion, McCain enjoys from his own backers. (And the size of Obama's crowds...)

2. The "Major League vs Little League" difference between Obama's infrastructure and his own.

6. How many voters (even Republican stalwarts) dread the idea of a virtual third Bush term.

12. How old he looks when he is acting "presidential" on the stump - and how incongruous it makes his message of change appear.

13. How powerful debates might be when the allegedly inexperienced Obama of allegedly questionable judgment goes toe-to-toe with McCain, even on national security, and is therefore deemed of sufficient strength and stature to be president by many.

Go see which ones you agree or disagree with.
