Rick Santorum's speech to the Republican National Convention was heavy on his "hands" metaphor. 

"I shook the hand of the American Dream," he said. "And it has a strong grip."

But it's hardly the first time hands have been involved in his campaign.

Rick Santorum's speech to the Republican National Convention was heavy on the "hands" metaphor.

But it's hardly the first time hands have been involved in his campaign. In fact, hands have been an ongoing theme for Santorum.

In Iowa in January, Santorum talked about his granfather's hands: "I'll never forget the first time I saw someone who had died. It was my grandfather. And I knelt next to his coffin, and all I could do at eye level was look at his hands. They were enormous hands. And all I could think was, 'Those hands dug freedom for me.'"

There was also a small controversy in February when news outlets played video of church-goers laying hands on Santorum while worshipping.

And when Santorum endorsed Romney, he declared "all hands on deck."
