Former House Speaker Newt Gingrich (R-Ga.) expressed amusement Thursday at the "Winning the Future" theme of President Obama's State of the Union, saying the president is on a path for failure.

Gingrich, a potential 2012 GOP presidential candidate, penned a 2005 book titled Winning the Future: A 21st Century Contract With America, and called Obama's choice of theme "ironically funny." Gingrich argued that the vision of government the president laid out falls well short of his goals.

"Sadly, there is no Obama plan for winning the future," Gingrich said in an op-ed published on Yahoo News. "President Obama is on a path to lose the future while pretending to change things."

Gingrich isn't the only one of Obama's potential Republican challengers to criticize his speech, but he's taken the unique opportunity to contrast the president's ideas with those in his own book. 

Gingrich said that Obama's speech "saddened" him because it contained both critiques of government and calls for greater spending that he found contradictory. 

"What was most depressing about President Obama's State of the Union address was not its big-government liberalism, its clever maneuvering to keep all the big government of the last two years or its failure to admit how much liberalism had failed to create jobs," he said. "What really saddened me about the President's State of the Union address was its shallowness and lack of serious dialogue."
