Longtime Republican foe of Washington Democrats Newt Gingrich threw his name into the ring of the 2012 presidential race, even as the White House said President Barack Obama hasn't opined on the GOP process.

No one person in the office of U.S. President can get changes done to improve America's future, Gingrich said on Wednesday as he formally announced his bid to become the Republican nominee for the 2012 Presidential race.

Gingrich, the former Republican House Speaker best known for his tempestuous battles with President Bill Clinton in the 1990s dismissed the power of the Oval Office as he courted supporters.

I want your help because no one person in the Oval Office can get this done, Gingrich said.

We Americans are going to have to talk together, work together, find solutions together and insist on imposing those solutions on those forces that don't want to change, he said.

Meanwhile, a White House spokesman said President Barack Obama has not said anything about the Republican process. Obama has already launched his campaign, with a series of high-priced campaign stops from coast to coast as he raises funds for what could be the most expensive Presidential race ever.

I've spent a lot of time with the President since I've taken this job, and I have not heard him discuss in private, even, that process. So I don't have anything to add to it, said White House Spokesman Jay Carney.

Gingrich said there's a much better American future ahead.

He said there would be more jobs, prosperity, health system, independent living and a decentralized federal government with power once again back with the American people and away from the Washington bureaucracy.

No one person can accomplish this. It can't be done from the Oval office. We have to work together, he said.

Gingrich said several weeks ago he was forming a formal committee to explore his a possible candidacy.
