Politico reports Santorum endorsed Liljenquist because he thinks it's time for a change in Washington, and Hatch has been there too long.
"It's not Orrin Hatch's seat. It wasn't my seat when I was in the United States Senate. Nobody owns it, your name is not inscribed on that seat,” Santorum said on CNN's "State of the Union." “The people of Utah, just like the people of every other state, have an opportunity every time to assess who's the right person at the time."
Santorum, who served with Hatch from 1995-2007, called the senator a “good man” but said Washington needs “people to say no,” like Liljenquist.
