Whenever someone claims to be an expert in something, generally that person is full of crap.
When an organization (selling a product) does so, the organization is generally blowing smoke up your hind end to see if you will buy their load of crap.
Pence also seemed like a decent guy whom I did not think was Vice Presidential material even though the Vice President has but three duties:
1. To preside over the joint session of Congress to count the electoral votes.
2. To be the president of the US Senate.
3. To assume the presidency upon the death or disablement of the President.
