Washington (CNN) - Likely 2012 Republican presidential candidate Rick Santorum joined the list of White House hopefuls using President Obama's re-election announcement as a platform to voice criticism of the current economic climate under Obama.
"We can't take four more years of the 'change' the Obama Administration has forced upon America," Santorum said in a release Monday. "The only thing that has changed is the amount of our debt, the size of our government, the loss of our freedom, the fewer jobs for those wanting work, the diminished stature of America, and an expensive military commitment without a clear national security purpose."
The former Pennsylvania senator, who has traveled extensively to early primary and caucus states, also criticized the president's record in office.
"The 'progress we've made' that the President refers to has nothing to do with improving the lives of Americans or providing a better future for the next generations. It is about moving an ideological agenda to grow the power of Washington over the average citizen," Santorum said.
Former Massachusetts governor and possible 2012 candidate Mitt Romney knocked Obama on Monday, tweeting, "@barackobama I look forward to hearing details on your jobs plan, as do 14m unemployed Americans."
Tim Pawlenty, former Republican governor of Minnesota, was the first presidential hopeful to respond to Obama's re-election announcement with his own video Monday morning that said a new president is needed to take America in "a new direction."
And former U.S. House Speaker Newt Gingrich said Obama is trying to "coerce and run over the American people" with his fundraising machine.
"I don't believe he can raise enough money to hide from the American people," Gingrich said in New Hampshire on Monday. "I think frankly he'll be a one-term president."
