President Barack Obama speaks Tuesday at a White House event titled "In Performance at the White House: Red, White and Blues."

There are 258 days until Americans choose who will be president for the next four years but signs are increasing that the Republicans are getting further from, not closer to unseating the president.

An Associated Press-GfK poll (PDF) released today puts President Barack Obama past the 50-percent favorability mark against all Republican contenders.

Before the general election has even begun, the president leads Rick Santorum by 9 percent, Mitt Romney by 8 percent and has a ten-point advantage over both Ron Paul and Newt Gingrich.

The results jive with a CBS poll released last week showing that the president’s approval rating is now above 50 percent as well.

According to the Associated Press, poll results continue to show ambivalence about and even disinterest in the Republican candidates. While Santorum has surged to a lead in some national polls, the AP-GfK poll shows he is about dead even with Mitt Romney, with the two at 33 percent and 32 percent respectively.

While 66 percent of Republicans polled in October were satisfied with the choices in the Republican nominating contest, only 60 percent now say so, according to the AP, which noted that 2 in 5 now say they are dissatisfied.
