Sarah Palin is promoting 7th CD candidate Sean Duffy's money bomb today on her Facebook page.

In an entry that criticizes the federal stimulus package the president signed a year ago, Palin writes about the need to send "Commonsense Conservatives" to Washington, D.C., singling out Duffy as one of the many "daring Davids" who will "take on entrenched Goliaths."

"On this first anniversary of the stimulus, let's send a message to the big-spenders in Washington by helping Sean Duffy unseat the author of the stimulus," Palin wrote. "Let's put government back on our side and get to work revitalizing America!"

Duffy issued a statement saying he was "absolutely thrilled" to have Palin's support, and his campaign says he's the first House challenger to be endorsed by the former Alaska governor and vice-presidential nominee.
