(CNN) — A majority of Americans think Sarah Palin is stepping down as Alaska's governor for political reasons, according to a new national poll, with a majority of Republicans now saying that they do not believe that Palin would be an effective president. Only 33 percent of Republicans questioned in a CBS News survey released Monday night say that Palin would have the ability to serve effectively as president. Last fall, 71 percent of registered Republicans felt that way.
"It's unclear whether the change in Republicans' view of Palin is the result of her decision to step down as governor, or whether the GOP rank-and-file felt they had to defend their party's vice-presidential nominee during the campaign but don't feel the same tug of party loyalty today," said CNN Polling Director Keating Holland. "Either way, this is bad news for Palin, whose first task in 2012, if she runs for the White House, will be to convince Republican primary voters to support her."
