Trump and Clinton looking to stay strong heading into March
Donald Trump and Hillary Clinton are cementing their status as front-runners with strong performances among the demographic groups at the core of their two parties.
It puts tremendous pressure on their rivals heading into delegate-rich March.
Exit polls show a surprisingly strong performance for Trump among Evangelical conservatives in South Carolina, that helped him notch another double digit victory and sweep all 50 delegates.
It was a grave blow to Sen. Ted Cruz, who invested heavily in his pursuit of religious conservatives only to finish a narrow third behind Sen. Marco Rubio.
For Democrats, Clinton's Nevada caucus victory over Sen. Bernie Sanders affirmed her strength among non-white voters, who, like white Evangelicals for Republicans, will play key roles in upcoming primaries.
