"We’re proud to join conservatives in Texas and throughout the nation in supporting your campaign to become the next senator from the Lone Star State," Palin wrote in response to a letter from Cruz, according to his campaign. “Your conservative principles, passionate defense of our Constitution and our free market system come at a time when these cornerstones of our freedom and prosperity are under attack. Our shared goal isn’t just to change the majority in control of the Senate, but to assure principled conservatives like you are there to fight for us.”

Cruz, who also won endorsements from Ron and Rand Paul, said he was honored to have Palin's support, calling her an inspiration to conservatives nationwide.
