Obama regrets not voting 'present'

On raising the debt ceiling in 2006.

A fight over raising the debt limit is looming, and the White House is trying to explain away the apparent contradiction between Obama’s previous opposition, and his position now that it must be increased.

Press Secretary Jay Carney said Monday that Obama believes his vote was a mistake. He said Obama now realizes that the debt ceiling is too important to be trifled with.

I guess the question is, was Brackets trifling with the national debt in 2006, or now? Or both?
