It's "possible" for me to rob the bank down the street.
Is that "proof" that I did?
You really don't get it, do you? You're the one making claims - you've got to provide the "proof".
You don't get it either is he making a claim that obama does not have any influence over his appointee the one who controls the department who collects the information for the unemployment numbers?
No, he's not.
He's making the claim that with an absence of any evidence, it's pretty ridiculous to assume that "Obama" is cooking the numbers, just because it's within the realm of possibility.
Who controls the labor department?
Simple question to answer.
