Despite the agreement that saved the nation from plunging off the fiscal cliff, most Americans are worried about the country's future.

A new survey from Gallup and USA Today found that 50 percent believe the country's best years are behind us.

More than three out of four say politics in Washington is causing serious harm to the country.

Americans also still have serious reservations about Obamacare. Four in 10 say it will make things worse while three in 10 say it will make things better.

Only 12 percent expect the fiscal deal to make things "a lot better" for them, while 21 percent say it will make things "a lot worse."
