From the excellent Hotline On Call:

“At the second polling place stop of the morning, Janet Huckabee stockpiled three or four snowballs and started a snowball fight with her husband, Mike Huckabee. She struck first but the scuffle, which lasted five minutes, ended with the candidate and his wife throwing piles of snow at each other before the governor’s hands got too cold to pick up anymore of the white stuff.

Then they returned to taking pictures with voters.
