Former Alaska Gov. Sarah Palin (R) on Wednesday came out against the tax-cut deal President Obama brokered with Republicans.

The potential 2012 presidential candidate endorsed a Twitter post that applauded Sen. Jim DeMint's (R-S.C.) criticism of the deal. 

"Thank you, @JimDeMint - DeMint comes out against tax deal, says GOP must do ‘better than this,'" reads the message from conservative commentator Jedediah Bila.

Palin cannot vote on the deal, which is also unpopular with liberals, but she is a major voice within the Republican Party and arguably its most well-known member. 

Under the proposed compromise, all of the expiring Bush tax cuts would be extended for two years in exchange for a 13-month extension of unemployment benefits and a 2 percent reduction of the payroll tax next year.
