As Hillary Clinton looks toward a potential 2016 presidential campaign, her personal image is eroding. A new NBC News/Wall Street Journal poll shows the number of people who have a positive view of Clinton has dropped from a high of 58 percent in December to 46 percent today. The 22 percent who have a "very positive" view of Clinton is lower than any time since the 2008 presidential campaign, and the 21 percent who have a "very negative" view of her is higher than at any point since then.
