The 2008 GOP vice presidential nominee also remains a force on the campaign trail, endorsing numerous fellow Republicans in the GOP primaries this year. But the big question remains: Does Sen. John McCain's running mate in the last race for the White House want to make her own bid for the top job in next presidential contest?
On July 3, 2009, the governor, who had 18 months left in her first term in office, announced "that I am not seeking re-election."
Palin went on to say that "I have determined it is best to transfer the authority of governor to Lieutenant Governor Parnell."
She stepped down on Sunday July 26. If anyone thought her resignation would be an end to the national fascination surrounding Palin, they would be mistaken.
Palin's visibility and income have skyrocketed, thanks to her best selling book, "Going Rogue," her contract as a contributor on Fox News Channel, her own TV show on TLC, and speeches that are believed to bring in $100,000 a pop. Her keynote address at the first National Tea Party convention in Nashville Tennessee in February was carried live by the cable news networks. A new book is due out in November, which is expected to be followed by a second national book tour.
Just in the past two weeks, her speaking engagements have taken her from California to Texas, Virginia, Georgia and Nevada, where Wednesday she served as keynote speaker at the International Bowl Expo in Las Vegas.
Palin has also been busy over the past year taking on the Obama White House and Congressional Democrats, getting her messages out on her Facebook page and Twitter.
Palin has remained a force in Republican party politics. She's endorsed a slew of candidates in the Republican primaries who've gone on to win their nomination battles. Among those she's successfully backed on the statewide level include Rand Paul in Kentucky, Nikki Haley in South Carolina, Terry Branstad in Iowa, Susana Martinez in New Mexico and Carly Fiorina in California.
Palin is still very popular among Republican voters, especially conservatives and Tea Party activists. But national polls indicate that her standing among all Americans is not so positive.
An NBC/Wall Street Journal poll conducted two weeks ago indicated that 33 percent of Americans hold a negative view of Palin, with 29 percent saying they see her in a positive light, and 24 percent saying they hold a neutral view of Palin.
While very successful so far in the GOP primaries, according to the survey, 52 percent of all voters said they would respond in a negative manner if they knew Palin endorsed a candidate they were considering voting for in the midterm elections.
As for the big prize, recent national polling does not look favorable to Palin. Only three in ten people questioned in a CNN/Opinion Research Corporation national poll from April thought Palin was qualified to be president, in line with other national polls conducted earlier in the year.
"People who loved her a year ago still love her, maybe even more," says Stuart Rothenberg, publisher and editor of the nonpartisan Rothenberg Political Report. "People who were doubtful about her abilities, skeptical about her skills or opposed to her haven't changed their minds."
