COLUMBIA, S.C. -- Sarah Palin says that if she lived in South Carolina, she would vote for Newt Gingrich in the state's presidential primary.
The former Alaska governor and vice presidential candidate told Fox News on Tuesday that she wants to see the Republican primary continue.
Palin says the GOP candidates are improving as the contest continues and adds that, in her words, "iron sharpens iron and steel sharpens steel."
Palin considered entering the presidential race last year but ultimately decided not to. She still holds sway among tea party activists.
Palin was the GOP's vice presidential candidate in 2008.
