John Thune's soft-spoken geniality is often considered a liability -- both when he was thinking about running for president and, now, in the Veepstakes.
But he tells The Hill that reputation is undeserved.
"I’m not somebody whose disposition and temperament is hostile. But once somebody throws the first punch, I’m all in."
As proof, he notes:
"There aren’t very many people I know of who ran against incumbent Democrats in back-to-back elections for the United States Senate.
You have to be fairly decisive and willing to attack and willing to go on offense."
