President Barack Obama's economic ratings have hit the lowest level of his presidency even as unemployment continues to decline and his administration has touted the creation of millions of jobs since 2009. Obama's underwhelming approval ratings come as Democrats are campaigning to keep control of the U.S. Senate and to take back the U.S. House just weeks before the 2014 midterm elections.

A CNBC All-America Economic survey released Tuesday shows only 24 percent of Americans are extremely or quite confident with Obama's economic record, down from 33 percent in June 2013, the previous low-point for the Obama administration. The survey found 44 percent of Americans had no confidence at all in Obama's economic policies. Obama's approval ratings declined among all demographics, and only 45 percent of Democrats expressed confidence with how he handled the 2009 global recession. 

One ray of hope for Obama and Democrats ahead of the midterm elections is that Americans like Congress even less than they like Obama. Only 11 percent of those polled said they were extremely or quite confident in Republican economic policies, compared with 16 percent support for Democrats in Congress. That could help Democratic lawmakers keep control of the Senate, though it likely won't make much of a difference in the Republican-controlled House, where voting districts favor the GOP.

The survey spoke with 805 adults from Sept. 25-28. It has a margin of error of 3.5 percentage points.

Former President Bill Clinton indirectly criticized the Obama administration's economic record while campaigning for Democratic U.S. Sen. Mark Pryor in his home state of Arkansas on Monday. "They are really running against the president, aren't they?" Clinton said of Republican candidates. "They see these polls, the president is unpopular in Arkansas and, yeah, the economy is coming back but nobody believes it yet because you don't feel it."

Unemployment has fallen from a high of 10 percent in 2009 to 6.1 percent this year. But Obama has acknowledged that his declining approval ratings could cost Democrats votes during the midterm elections. He said: "I am not on the ballot this fall. Michelle’s pretty happy about that. But make no mistake: These policies are on the ballot. Every single one of them.”
