Obama's road to nowhere

Obama told the nation he needed billions of dollars in stimulus money for shovel ready work such as building roads and bridges.   Apparently the money has been spent and the economy has not been stimulated in the least.  So what happened to the money and why is Obama asking for more?  More specifically the Obama White House has recently indicated approval for an additional $75 billion in new stimulus funds for roads and other construction projects.  Road construction has been touted as the shovel ready work that was going to save America and was going to be magically funded by the stimulus slush fund.  The facts are in and the stimulus money spent on road construction has had absolutely no positive effect on the economy or in reducing unemployment in America.   Obama and his administration are on the verge of becoming a complete failure and a laughingstock in rational circles.
