(CNN) - The Barbara Bush-Sarah Palin verbal spat continued Wednesday with Palin's response to the former first lady, who on Monday said she should stay in Alaska.
"I don't think the majority of Americans want to put up with the blue-bloods," Palin said in a radio interview on the Laura Ingraham Show Wednesday. "With all due respect because I love the Bushes, the blue-bloods who want to pick and choose their winners instead of allowing competition."
The former Alaska governor said she will not be suppressed by leaders of the Republican Party, who she said are ignoring "the will of the people." She also called their statements "inefficient," "unprofessional" and "immature."
Wednesday's interview coincides with the release of her new book, "America by Heart."
However, on conservative Sean Hannity's radio show Tuesday, Palin said if her 2012 candidacy were hurting the Republican Party she would step aside.
"If I get in the way of that cause, I don't need a title, I don't need a position," Palin said.
Palin has repeatedly left the door open to a presidential run in 2012, even telling ABC's Barbara Walters that she could beat Obama in the next election. In the meantime she is in the midst of a national book tour, which will include stops in Iowa and South Carolina, sites of early presidential primaries and caucuses.
