Trump by 22
The CBS News Battleground Tracker poll shows that Donald Trump keeps a large lead in South Carolina, bolstered by support from conservatives and also from evangelical voters, who make up a large share of the electorate here.
Ted Cruz is in second place, but well behind Trump. Cruz has the support of those who consider themselves very conservative, but trails Trump among all conservatives as well as moderates.
John Kasich has gotten a little bounce out of his surprisingly strong showing in New Hampshire, but he may be limited here by the fact that evangelical voters are not as strongly in support of him as non-evangelicals.
For Trump voters, who have been relatively steadfast in their support over the last few months, the percentage who say they've firmly decided on Trump has increased. Trump's lead among evangelicals is up from January, and he has widened his lead among conservatives, too.
Trump now in the 40s in South Carolina. This is his biggest lead since July of 2015
