Former Alaska Gov. Sarah Palin (R) has recorded a last-minute robocall for Kelly Ayotte's Senate campaign in New Hampshire.
"Kelly is one tough 'Granite Grizzly' who has broken barriers, fought off and locked up criminals, and stood up for New Hampshire families," Palin said in the automated message that will go out to GOP voters ahead of Tuesday's primary.
Palin calls Ayotte "the true conservative running for the U.S. Senate in New Hampshire," in the call. "She will cut spending, eliminate earmarks, protect your 2nd Amendment rights and bring some much-needed Granite State common sense to the Senate."
Unlike in Delaware's Republican Senate primary, where Palin is backing conservative commentator Christine O'Donnell, her pick in New Hampshire is staring down a surging conservative challenger.
Palin endorsed Ayotte in a post on her Facebook page in July, but Ovide Lamontagne appears to have gained ahead of the primary.
Self-funding businessman Bill Binnie and Jim Bender are also vying for the Republican nod for the Senate seat of retiring Sen. Judd Gregg (R-N.H.).
Lamontagne has been massively outspent by Ayotte and Binnie, but he won the endorsement of Sen. Jim DeMint (R-S.C.) late Friday and is claiming last-minute momentum.
Along with backing from Palin, Ayotte has touted her endorsements from Sen. Tom Coburn (R-Okla.) and former Sen. Rick Santorum (R-Pa.).
