President Barack Obama plans more economic stimulus measures to bring down the high U.S. unemployment rate, while cutting the bulging budget is a longer-term challenge, Reuters quoted a top White House economic aide as saying. "We are ... talking about actions right now to jump-start job creation," White House Council of Economic Advisers Chairwoman Christina Romer said on CNN"s "State of the Union. "You don"t get your budget deficit under control at a 10 percent unemployment rate," she said. Beating back unemployment will be a key yardstick by which U.S. voters will measure Obama"s success in November congressional elections and will go a long way to determining his own long-term political future. Also troubling to many is a budget deficit that has ballooned from spending aimed at cushioning workers and businesses through the worst recession in decades. "We have to do something," Romer said. "There are more targeted actions that we think absolutely will help." Obama will focus is on getting the U.S. fiscal house in order over the longer run, she said. Unemployment was stuck at 10 percent in December and businesses cut another 85,000 jobs, the lingering after-effects of the devastating financial crisis that triggered an economic global recession. With Obama"s popularity drifting down to around 50 percent, his Democratic party is expected to lose seats in Congress in fall elections unless the White House can engineer a convincing economic turnaround. Limiting the president"s room to move is a federal budget deficit that hit a record $1.4 trillion in fiscal 2009. The president has also promised not to raise taxes on U.S. families making less than $250,000.
