Former US vice-presidential candidate Sarah Palin has called for limited government and a return to, what she called, common sense conservative principles.
Ms Palin was addressing the first national convention of the 'Tea Party' movement.
In a wide ranging speech, Ms Palin said the country was drowning in debt and she said Washington should make real spending cuts.
She pointed to the victory in Massachusetts last month when Republican Scott Brown won a senate seat held for more than four decades by Democrat Ted Kennedy as a sign that Republicans were on their way back up.
She accused the Obama administration of being weak on national security and 'out of touch with the enemy that we face'.
Ms Palin also took a swipe at Obama's foreign policy, and charged he had been too slow to jumpstart the ailing US economy.
The 'Tea Party' movement is called after the protest against British taxation, known as the Boston Tea Party, which was one of the triggers of the US revolution against colonial rule.
