Hillary Clinton to visit Durham high school

A planned second stop at Broughton High School in Raleigh was canceled Wednesday. Clinton will rally in Chicago Thursday evening instead.

Both North Carolina and Illinois hold primaries next Tuesday, March 15.

A WRAL News poll released this week shows Clinton with a commanding 57 percent to 34 percent lead among likely North Carolina Democratic voters over U.S. Sen. Bernie Sanders of Vermont.

Clinton has sizable leads among both men and women and wins by a landslide among black voters, 74 percent to 20 percent.

As he has shown throughout his campaign, Sanders' strength lies with young voters. He holds a 64-34 percent advantage among voters ages 18 to 34 in the WRAL News poll. Once voters hit age 35, however, the polling clearly favors Clinton, with anywhere from 18- to 51-point margins in her favor.

Clinton's husband, former President Bill Clinton, on Monday kicked off a week of campaigning in North Carolina by presidential contenders in advance of the March 15 primary with a stop in Raleigh.

Republican front-runner Donald Trump appeared in Concord on Monday and had a Fayetteville rally on Wednesday night.

Trump's closest rival, Ted Cruz, made Tuesday stops in Raleigh and Kannapolis.

Clinton's Democratic rival, Sanders, will make his own Raleigh stop on Friday.
