RELEVANT EXPERIENCE: One dwarfs the other, dramatically.
Is it possible to "just add water" and voila! instant management skills - or does it take years to hone this skill to the level where one can be effective. From my years of experience, and personal frustrations learning management, I absolutely believe that it takes years and years to learn management. We cannot afford to have a President who needs lots of on the job training.
If one rates experience and success in managing and actually running businesses, this is how the candidates would stack up. (This is not from a prejudiced point of view. It is an assessment, which you, of course, will have to examine for its substance. It is based on facts and is very, very clear:
Romney 10 Brief video clips:
Obama 2 (He has achieved some experience from being in the White House,
but as an "amateur" - see Confidence Men, Suskind history
based on 700 interviews - very revealing of what actually is going
Gingrich 1 Also "idea man", but we need a man who gathers more info and
reasoned consensus and then implements effectively; not a
man who is erratic and at times alienating.
Santorum 1 A "social values" strong advocate to the degree it alienates
people. Excessive focus in that area provides a conflict with
good, balanced management.
While there may be some disagreement on the rating, I think it would be slight, as facts are facts (and opinions are not facts!).
