Sricki,

This is really a great question. I can't speak for others but I will share my perception with a imperfect analogy.  For the purposes of this discussion, lets assume Clinton's claim of "35 years of experience is actually true" (when I do the math and look at actual roles I think that statement is largely myth, but let's just pretend it's true for  this discussion)

For me it's like high school.  I remember two teachers, the fist teacher was 55 years old, had been a teacher for 30 years, had a perfect syllabus and all the right books.  She had a well decorated class, the support of the school administration and the parents really liked her.  This teacher taught the same thing year after year and was a stickler for the mechanics of writing.  She focused on sentence structure, punctuation, formatting and timeliness.  She had a plan for every day, she had a plan.  She was an effective, even good teacher but never pressed me for the thought behind the thought, never pushed me to deeper work.  

The second teacher, was 35 years old, had been a teacher for 15 years, had kind of a messy class, was often in hot water with the administration, discussed topics many parents thought were "inappropriate" an evolving syllabus that might change depending on what was going on in the world.  She had a 5 grades slots set aside for what she called "open essays".  Each semester this teacher expected us to find 5 experiences in every day life to write about.  

---Some of my topics, (The shame of being evicted from our apartment, the death of my grandfather and associated family dynamics, titles "the lies we must tell" (though a minister my grandfather was FAR from a perfect man)---

I once wrote a technically strong soulless paper for the second teacher that after reading she pulled me aside to tell me was "a bullshit waste of time" and that she expected more, far more from me.  

The second teacher, challenged, cajoled, ridiculed, inspired and tested me, think "Finding Forester"

I liked the first teacher, I loved the second.  

Love isn't really a word that should apply to politicians but as I mentioned this is a imperfect analogy.  

I don't love Obama, I love my family but I hope you get the point.

People rightly like Clinton but for those who connect, the feelings about Obama are on a different scale.  

I think it really boils down to what people want in their leaders.  It's not a right or wrong question, more a neat and organized with a perfect syllabus vs. "that was bullshit".

I respect people of both preferences but I love my brother and sisters who fight to break the machine.    

Obama just happens to be political figure I hope can be the instrument to inspire the change I already desire, a national muse of sorts.
