An increase in the debt ceiling is needed to keep the August Social Security checks from being delayed or reduced. From the Los Angeles Times:
Republican leaders in the House have begun to prepare their troops for politically painful votes to raise the nation's debt limit, offering warnings and concessions to move the hard-line majority toward a compromise that would avert a federal default. ...
At a closed-door meeting Friday morning, GOP leaders turned to their most trusted budget expert, Rep. Paul D. Ryan of Wisconsin, to explain to rank-and-file members what many others have come to understand: A fiscal meltdown could occur if Congress fails to raise the debt ceiling.
House Speaker John A. Boehner of Ohio underscored the point to dispel the notion that failure to allow more borrowing is an option.
"He said if we pass Aug. 2, it would be like 'Star Wars,'" said Rep. Scott DesJarlais, a freshman from Tennessee. "I don't think the people who are railing against raising the debt ceiling fully understand that."
The warnings appeared to have softened the views of at least some House members who, until now, were inclined to dismiss statements by administration officials, business leaders and outside economists that the economic impact would be dire if the federal government were suddenly unable to pay its bills.
Freshman Rep. Steve Womack (R-Ark.) said the presentation about skyrocketing interest rates that could result from downgraded bond ratings was "sobering."
