(Fox News) — More American voters disapprove than approve of the job President Obama is doing. Likewise, if making a choice today, more voters say they would back someone else for president in 2012 than say they would give Obama a second term. Who would that someone else be?

Former Massachusetts Gov. Mitt Romney remains Republican primary voters’ preferred candidate. He’s also the GOP contender more voters see as likely to do a good job in the White House.

These are some of the findings from a Fox News poll released Wednesday.

Currently 42 percent of voters approve of Obama’s job performance and 48 percent disapprove. Last month, before the agreement on the nation’s debt limit was finalized, 45 percent approved and 46 percent disapproved (July 17-19, 2011).

The drag on the president’s rating these days is not only lower approval among Democrats, which currently stands at 77 percent, but also a record-low 31 percent approval among independents. Approval among Republicans is 6 percent — matching a previous record-low in October 2010.
