[N]early eight months after its passage, a large majority of the stimulus has yet to start impacting the economyas was the plan. And as was also the plan, the most visible parts of the stimulus are only taking effect now and will remain active through 2010. As you drive around town, it's difficult to visualize tax rebates or aid to statesthe fast-acting components of the stimulus. But as I drive around my town today, I can see workers laboring at a $4 million, stimulus-backed road project that is just getting started and will run through the spring of 2011...the debate over whether the stimulus worked will ultimately be settled in 2012as voters go to the polls and economists crunch the 2011 data. Until then, we should avoid jumping to rash conclusions.
