Failed Obama Pork bill to cost even more or Officials Say Stimulus Bill To Cost $75B More WASHINGTON -- Last year's $787 billion economic stimulus bill is going to be even more expensive -- $75 billion more. The new Congressional Budget Office estimate, released Tuesday, provides more ammunition for Republicans who say the stimulus has been long on spending and short on creating promised jobs. The additional cost also eats into the savings forecast from the budget freeze President Barack Obama is expected to propose Wednesday night during his State of the Union address. Almost half of the additional cost, $34 billion, is because the food stamp program won't be able to take advantage of lower-than-expected inflation rates and will instead have benefits set by the stimulus bill. Higher unemployment insurance costs added $21 billion to the bill, and stimulus-subsidized bonds to pay for infrastructure projects have proven more popular than expected with state and local governments.
