Sarah Palin endorses Christine O'Donnell in Delaware

Sarah Palin today threw her support behind "Tea Party" favorite Christine O'Donnell in Tuesday's Republican primary in Delaware. O'Donnell faces veteran Rep. Mike Castle.

Palin, the GOP 2008 vice presidential nominee, made it official on her Facebook page this afternoon:

The wave of positive change can really sweep across our land with the election of Constitutional Conservatives who promise to use common sense and rein in the federal government spending! Please support Christine O'Donnell in Delaware. She will support efforts for America's energy security, patient-centered health care reform, cutting government waste, and letting the private sector thrive and prosper! We can't afford "more of the same" in Washington. Christine will help usher in the real change we need to get America on the right track.

O'Donnell thanked Palin with this tweet:

Thank you for your clear confidence in my candidacy. Strong conservative women will take our country back!

O'Donnell's backers hope to repeat the success of Alaska's Joe Miller, who secured the GOP Senate nomination last month after a Palin endorsement and an influx of last-minute spending by the Tea Party Express. The Tea Party group has reported spending nearly $60,000 so far to aid O'Donnell, federal records show.

USA TODAY's John Fritze recently pointed out that Palin's record picking winners this year has been mixed.
