Aides to McConnell said they have yet to receive a cost estimate for the measure. But the nonpartisan Congressional Budget Office recently forecast that a similar, slightly more expensive package that includes a full repeal of the estate tax would force the nation to borrow an additional $3.9 trillion over the next decade and increase interest payments on the national debt by $950 billion. That’s more than four times the projected deficit impact of President Obama’s health-care overhaul and stimulus package combined.

“We have a spending problem. We spend too much. We don’t have a taxing problem. We don’t tax too little,” McConnell told reporters Tuesday. “And if we want to begin to get ourselves out of this economic trough that we’re in, the only way to do that is to grow the private sector.”
