Speculators! Duck and cover!
In the manner Obama says it, a novice English-speaker might assume "to speculate" means something like "to consume the deceased carcass of a human for nourishment", and I'm not sure his intent with that word is metaphorically far off.
It makes one specu -- wonder: Has Obama ever committed speculation? Says Merriam-Webster:
1 a : to meditate on or ponder a subject : reflect b : to review something idly or casually and often inconclusively
I've never read a more fitting definition of "liberal arts college"; I'm gonna assume Obama was a big speculator at Occidental and Harvard.
2: to assume a business risk in hope of gain; especially : to buy or sell in expectation of profiting from market fluctuations
Yup! That sounds like what he has previously referred to as "stimulus."
1: to take to be true on the basis of insufficient evidence : theorize
Ding Ding Ding!!!
2: to be curious or doubtful about
So he's guilty of three of these.
