The crashing economy has prompted Obama to begin acting presidential even before Inauguration Day. He has declared his intention to develop an economic stimulus package aimed at saving or creating 2.5 million jobs and promoting infrastructure improvements, environmentally friendly investments and health-care efforts, and he wants that package on his Oval Office desk for signing into law soon after he arrives at the White House. "We don't intend to stumble into the next Administration," Obama told reporters on Tuesday in Chicago. "We are going to hit the ground running." But unlike on Monday, when Obama's naming of his economic team accompanied a nearly 400-point boost in the Dow Jones industrial average, during Tuesday's conversation with reporters, major market indicators slumped but later began to rise again. Investors, no doubt, will be paying close attention when Obama holds a third press conference in as many days on Wednesday.
