President Barack Obama is acknowledging that Europe's economic situation could have a spillover effect on his own re-election prospects.

As he wrapped up the Group of 20 economic summit of world leaders, Obama expressed confidence in Europe's ability to right its own financial ship. He said he was hopeful that voters would validate his own efforts come November if he stayed focused on strengthening both the U.S. and world economies and creating more jobs at home.

"I've consistently believed that if we take the right policy steps, if we're doing the right thing, then the politics will follow, and my mind hasn't changed on that," the president said a news conference in this Mexican resort Tuesday at the close of what is expected to be his last foreign trip before the November election.

The president returned early Wednesday to Washington, where a tough re-election fight and a shaky economy awaited him.
