Republican presidential hopefuls will square off once more during Thursday’s Fox Business debate in South Carolina, where they’ll have one of their last chances to knock out a rival on live television, less than three weeks before the crucial Iowa caucuses. Unlike the previous Fox Business debate in November, where both candidates and moderators struck a decidedly civil tone, the gathering on Thursday evening is likely be more of a raucous affair. With what appears to be a toss-up in polling between Trump and Cruz in Iowa, and a bare-knuckle brawl for the establishment lane between multiple candidates in New Hampshire, campaigns will be under significantly more pressure to land solid hits against their rivals for the GOP nomination.
