Anyone in public office for more than a nanosecond is likely to have words and deeds come back to haunt them. New political realities sometimes demand a new world view 180 degrees from the old one. And then comes the explanation.

President Barack Obama, who is urging Congress to raise the debt ceiling, is finding his 2006 Senate vote against raising the debt limit when George W. Bush was president has come back to bite him. OBAMA/

The White House has decided to confront the discrepancy head-on.

Asked about the five-year-old vote, White House spokesman Jay Carney said the president “now believes it was a mistake.”

And then Carney proceeded to inject the fear of calamity into the debate, saying failure to raise the debt limit would be “Armaggedon-like,” “devastating,” “dangerous,” “catastrophic,” and let’s not forget “calamitous.”

In 2006, Obama said: “Increasing America’s debt weakens us domestically and internationally. Leadership means that ‘the buck stops here.’ Instead, Washington is shifting the burden of bad choices today onto the backs of our children and grandchildren. America has a debt problem and a failure of leadership. Americans deserve better.”
