(CNN) - A new national poll suggests that a majority of Americans are considering voting against President Barack Obama in 2012, but the survey indicates Obama would come out on top if Sarah Palin is the Republican presidential nominee.
According to Politico/George Washington University Battleground poll, 38 percent of those questioned say Obama deserves reelection as president, with 44 percent saying they will vote to replace Obama, 13 percent saying they will consider voting for someone else, and six percent unsure.
The results of the survey are similar to a CNN/Opinion Research Corporation survey conducted early last month, in which 45 percent of registered voters said they would back Obama for re-election with 50 percent saying they would back the Republican presidential nominee.
According to the Politico poll, if the 2012 presidential election were held today and Palin was the GOP nominee, 42 percent say they would definitely, probably, or maybe vote for the former Alaska governor and 2008 Republican vice presidential nominee, with 51 percent saying they would definitely, probably or maybe vote for Obama. Eight percent are undecided.
Fifty-eight percent of those questioned say Palin's actions since stepping down as Alaska governor in the summer of 2008 have made them less likely to vote for her if she runs for president, with 31 percent saying her actions have made them more likely to support her.
The Politico/George Washington University Battleground poll was conducted September 19-22, with 1,000 registered voters questioned by telephone. The survey's overall sampling error is plus or minus 3.1 percent.
