Former Alaska Gov. Sarah Palin (R) on Tuesday commended House Budget Committee Chairman Paul Ryan's (R-Wis.) budget, calling it "Serious & necessary."

Palin, a potential 2012 presidential candidate, said that Ryan's proposal is a good start (and linked to an op-ed from December when she praised Ryan's previous budget plan, a "Roadmap for America's Future").

She tweeted:

There is hope! Serious & necessary leadership rolls out serious & necessary reform proposal. Good start (from Dec.

Ryan's budget proposal has already received praise from potential presidential candidates such as former Minnesota Gov. Tim Pawlenty (R) and former Sen. Rick Santorum (R-Pa.)

Their statements on Ryan's budget will be closely scrutinized, because observers have said it could loom large over the campaign landscape. Pawlenty was the first possible candidate to release a statement on the budget.

"It will become the 2012 Republican platform, no matter who is the nominee," New York Times columnist David Brooks wrote Monday.

Palin has said she remains interested in running for president in 2012, but has not yet said when or if she will officially announce her intention to run.

Ryan's plan will slash $5.8 trillion from current spending levels over 10 years, but would not balance the budget for at least two decades. It also proposed huge reforms to Medicare and Medicaid that he said would save the programs, and that Democrats say would hurt the elderly and poor.
