In more news from the campaign trail, new polls find Democratic candidates Bernie Sanders and Hillary Clinton are in a dead heat heading into the Nevada caucus this weekend. A new CNN poll shows 48 percent of likely voters support former Secretary of State Hillary Clinton, while 47 percent support Vermont Senator Bernie Sanders. In what’s being seen as a victory for Bernie Sanders, the most powerful labor union in Nevada, the Culinary Workers Union, has decided to withhold its endorsement ahead of the caucus. It had been assumed that the 57,000-member union would endorse Hillary Clinton.
