Predictions of possible jobs are always fraught with complications, guesstimates and fuzzy math, so they often should be taken with a grain of salt. No one really knows exactly how many jobs will be created. So maybe the president is right to be skeptical.
But the president shouldn’t pick and choose how he cites job-creation numbers. Perhaps he is tipping his hand on what he secretly thinks of the Keystone XL by citing a low-ball figure, generated by the pipeline’s opponents, but he should stick to using the official government estimate. (His 2,000-job figure is actually slightly lower than the Cornell estimate.)
Otherwise, the president ironically seems to be signaling that even his own government does not produce the “most realistic” estimate that should be used by reporters.
