Generational cohort trends are just that - trends.
FYI - the census bureau has been known to change the dates on their classifications within living memory. The boomer cutoff used to be 1960 and 61-84 was Gen X.
And if you can't figure out that Obama identifies with the impulses and politics of 60's radicalism and that Palin identifies with the can-do independence of Reaganism, then your arteries have hardend a tad too much.
Here's a fun read on the subject.

Have a great day.
If we all just make up definitions and people like you start reading minds, describing how various public figures internally identify with various generations that they are not of, then it becomes impossible to answer any idiot that starts throwing the word boomer around.
This reminds me of a (young) blogger that I like, posting a picture of the Chicago Seven and starting a thread about them and their boomer ways and Ayers and Dohrn. None of them were boomers and their birth dates went all the way back to 1915.
