LOS ANGELES (AP) — Stung by plunging approval numbers at a low point in his presidency, President Barack Obama is urging donors to buck up while making a thread-the-needle appeal for bipartisanship with Republicans even as he calls for replacing the House GOP majority and holding his Democratic edge in the Senate.

Obama is seeking to gain back his political standing in the aftermath of his administration's botched launch of health care enrollment by defining himself as a pragmatic victim of tea party conservatives. At the same time he is casting his policies on the economy and immigration as popular remedies that could win bipartisan support.

"Right now in this country there is at least one faction of one party that has decided they are more interested in stopping progress than advancing it, and aren't interested in compromise or engaging in solving problems and more interested in scoring points for the next election," he told Democratic donors in San Francisco on Monday.
