Trump draws barbs over response to David Duke

LEESBURG, Va. (AP) — The final-days sprint to Super Tuesday has erupted into a feud over a white supremacist as Donald Trump's Republican rivals scramble to halt the billionaire New York businessman from becoming an "unstoppable" force in the 2016 presidential contest.
Ted Cruz and Marco Rubio continued to hammer the GOP front-runner's character and lack of policy specifics in a series of attacks Sunday while courting voters across the South. But it was Trump's refusal to denounce an implicit endorsement from former Ku Klux Klan leader David Duke that dominated the narrative less than two days before Republican voters across 11 states head to the polls.
