Washington (CNN) - President Barack Obama's approval rating is down to 45 percent, driven in part by growing dissatisfaction on the left with the president's track record in office, according to a new national survey.
A CNN/ORC International Poll also indicates that the Republican "brand" is taking a beating in the minds of Americans.

The survey's Friday release comes as the Obama administration and top congressional officials continue talks on a potential deal tying roughly $3 trillion in new savings over the next decade to an increase in the nation's debt ceiling. If Congress and the President fail to raise the country's $14.3 trillion limit by August 2, Americans could face rising interest rates, a declining dollar and increasingly jittery financial markets, among other problems.
According to the poll, the president's 45 percent approval rating is down three points from June. Fifty-four percent of people questioned disapprove of how Obama's handling his duties, up six points from last month. His 54 percent disapproval rating ties the all-time high in CNN polling that the president initially reached just before last year's midterm elections.
"But drill down into that number and you'll see signs of a stirring discontent on the left," says CNN Polling Director Keating Holland. "Thirty-eight percent say they disapprove because President Obama has been too liberal, but 13 percent say they disapprove of Obama because he has not been liberal enough - nearly double what it was in May, when the question was last asked, and the first time that number has hit double digits in Obama's presidency."
Looking at that figure another way, roughly one in four Americans who disapprove of the president say they feel that way because he's not been liberal enough.
Obama's approval rating among liberals has dropped to 71 percent, the lowest point in his presidency. And the number of Democrats who want the party to renominate Obama next year, now at 77 percent, is relatively robust by historical standards but is also down a bit since June.
"It's likely that this is a reaction to some of Obama's recent actions, including his willingness to discuss major changes in Social Security and Medicare as part of the debt ceiling negotiations," adds Holland.
Some congressional Democrats appeared to be on the verge of open revolt against their own president Thursday night after hearing some of the details in the $3 trillion plan - a package many of them contend does not do nearly enough to ensure wealthier Americans share in the burden of stemming the tide of Washington's red ink.
Those Democrats are desperately trying to protect some of their party's primary legacies - entitlements such as Social Security and Medicare, programs forged at the height of the New Deal and Great Society.
On the other side of the negotiating table, the poll indicates that GOP is also not faring all that well. Fifty-five percent say they have an unfavorable view of the Republican party, a seven-point increase since March. The Democratic party's favorable rating is not much better, but it has held steady.
And only 37 percent say the policies of the Republican leaders in Congress would move the country in the right direction - a nine-point drop since the start of the year, when the GOP took over control of the House of Representatives.
"Although most Americans say that Obama is not doing enough to cooperate with the GOP, even more say that the Republicans need to cooperate more with the president," says Holland.
The poll was conducted for CNN by ORC International on July 18-20, with 1,009 adult Americans questioned by telephone. The survey's overall sampling error is plus or minus three percentage points.
