Does it mean "in an improper time (makes his image) as extremly greedy and in a fine day as filshy rich"?

And what does "Spock-like mind" mean?


Context:


Here's the problem: the one time in his cautious, careful, risk-averse candidacy that Romney gambled, he lost. Putting Paul Ryan on the ticket has been a disaster. Ryan's budget ideas -- voucherizing Medicare, privatizing Social Security, gutting education and giving tax breaks to the rich -- are toxic. The Romney-Ryan budget plan has cemented Romney's image as Gordon Gekko on a bad day; Thurston Howell III on a good one.
Romney's aides are right when they tell the press a debate is a series of moments, and they are wise to try to craft some moments. But they are fools for telling The New York Times: "(Romney's) strategy includes luring the president into appearing smug or evasive about his responsibility for the economy."
First, let me assure you our president reads The New York Times and has almost certainly deployed his Spock-like mind on avoiding smugness or evasion. Any strategy that relies on your opponent to err is a hope, not a strategy.
