From wikipedia:
The Twelfth Amendment to the United States Constitution states that "no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States."[4] However, unlike the two-election limit imposed on the Presidency by the Twenty-second Amendment to the United States Constitution, there is no restriction of the number of terms a person can serve as Vice President.
Thus, to serve as Vice President, an individual must be: * a natural born U.S. citizen not younger than 35
* must have been living in the U.S. for at least 14 years[5]
Other than that, our founding fathers put no other restrictions on qualifications to be the vice-president. Anything else is just opinion. I like Palin because she makes the Republican ticket stronger and puts a young conservative in a powerful position.
That she makes the ticket stronger, is opinion.
The Twelfth Amendment [qualifies Palin to be VPOTUS]
If we're to be disingenuous, please define "powerful position." (Is it so described in the Constitution? Or can just anyone qualified per the 12th Amendment handle it?)

in which Gov. Palin says "I still can't answer that question until somebody answers for me: What is it exactly that the VP does every day?"
