Pawlenty: Santorum 'lashing out'

After Mitt Romney won all three primary contests on Tuesday, former Minnesota governor and Republican presidential candidate Tim Pawlenty said, "This race for the nomination, as a practical matter, is over."

He told CNN's Wolf Blitzer he hopes Rick Santorum leaves the race now to help unify the party. "You can clearly see that Mitt Romney's on the trajectory to be the Republican nominee. There's no question about that," said Pawlenty when asked what he thought about Santorum's plan to continue campaigning.

When Blitzer questioned him about the possibility of being Romney's running mate, Pawlenty responded, "I've taken my name off the list. I've been down that road before."
