Is the federal stimulus creating jobs? Saving jobs? Is there any way to know--or get a politically unbiased answer? Since February, when the administration suggested the $787 billion stimulus could create or save 3.5 million jobs, the economy reportedly has lost 1.6 million jobs. This week President Obama said the stimulus has saved 150,000 jobs, and, well, would you settle for 600,000 new ones by the end of summer? Bring on the skeptics! "Today I saved 150,000 jobs," barks Big Dog's Weblog. "There are now 150,000 people who will continue to work because of me. No one can prove I did not, because there is no way to measure a 'saved' job." "Here's an important note to my friends in the news media," writes Tony Fratto at the CNBC Guest Blog. "The White House has absolutely no earthly clue how many job losses have been prevented because of the stimulus bill. None."
