Now that voters in Iowa and New Hampshire have made their decision, we move on to other states -- and three of those states voting in the next month are Arkansas (on March 1st), Michigan (on March 8th), and North Carolina (on March 15th). Hillary Clinton still looks very strong in those three states -- leading Sanders by 32 points in Arkansas, by 32 points in Michigan, and by 26 points in North Carolina.
