Sarah Palin Rails Against Obama, Issues Warning To Tea Party In New Hampshire Speech (VIDEO)

(AP/The Huffington Post) MANCHESTER, N.H. — Sarah Palin says the Tea Party needs to play a larger role in the 2012 presidential race.

Speaking to Tea Party activists Monday afternoon, the former Alaska governor said she wants conservatives to put aside internal squabbles and unite against President Obama.

Palin's visit -- her second to the Granite State in three months -- stoked supporters' hopes she will enter the presidential race. But she says she still hasn't made up her mind.

"They talk about the spending problem and yet Obama keeps spending more," the former governor said during a speech in the key primary state, Amherst Patch reports. "Enough is enough!"

She said cynics will keep mocking the Tea Party, but they can't let that get in their way.

"History is on the side of bold and courageous reform, and this movement is reform," Palin said.

"Now is the time to grow this movement," she added. "We need to understand that there are more independent Americans who want to be heard."

Politico reports that Palin issued a warning to Tea Party supporters on the issue of division and "media-incited internal quarrels." She explained, "We simply don’t have time to be bogged down in internal conflicts and friendly-fire conflicts."

Palin spoke to hundreds of conservative activists -- many of them from out of state -- gathered in New Hampshire's largest city for a Tea Party Express rally.

"At this late stage, there's been so little infrastructure work for a potential candidacy, I think this is simply Sarah Palin wanting to be part of the process and to help shape the debate for the presidential campaign," said Michael Dennehy, who led Sen. John McCain's presidential campaign four years ago, but is uncommitted this year. "At some point immediately -- meaning the next week or two -- she's going to hurt herself badly if she does not announce that she's not going to run for president."

The head of prominent Granite State conservative think says there is a growing sense of indifference among local conservatives.

"If she had done it right she could be popular here," said Kevin Smith, executive director of Cornerstone. "But I don't feel a lot of energy or enthusiasm here about a Palin run. Voters here in this state, who frankly have been taking this primary seriously since the beginning of the year, are indifferent."

That said, she drew hundreds of supporters to Monday afternoon's rally. And she was interrupted once with chants of, "Run, Sarah, run."

"I appreciate your encouragement, I do," she said, offering no more insight into her presidential ambitions.
