Sarah Palin didn't say whether she would seek the Republican presidential nomination, but she didn't rule out a run on Saturday when speaking to Tea Party faithfuls in Iowa.

Standing on stage in rain-dampened Iowa field Palin made it clear she has no intentions of falling in line behind one of the party's leading candidates, and also criticized U.S. President Barack Obama.

I want to tell you what my plan is, Palin said before going to speak in general terms. My plan is a bonafide, pro-working-man's plan. My plan is about empowerment. It's about states, entrepeneurs, and mostly the empowerment of you. Yes, we need sudden and relentless reform and that will return power to we the people.

Palin repeatedly condemned crony capitalism but didn't criticize any GOP candidates by name. Instead she grouped them with the permanent political class, and said their campaign proposals were vague.

She noted that while Obama is on track to raise a billion dollars for his reelection campaign, Republican candidates have also managed to raise mammoth amounts of cash.

The former vice presidential candidate warned tea party activists that they must keep tabs on what they owe to their big-spending campaign donors.

We need to ask them too, what, if anything, do their donors expect from their investments, Palin said. Our country can't afford more trillion-dollar thank-you notes to campaign backers.

Though she is keeping people guessing about her presidential bid, Palin said she intended to use political muscles she had in the 2012 campaign.

The challenge is not simply to replace Obama in 2012, Palin told the crowd of about 2,000, but the real challenge is who and what we will replace him with.

Palin even gave her own plans on keeping money in the government's coffers.

She said to offset the loss of government revenue she would eliminate corporate welfare - the loopholes and bailouts.

Palin said the bottom line is We need sudden and relentless reform, and that will return power to we, the people.
