Thom Hartmann looks at several studies that found the trend of increased violent deaths when Republicans are in power. One researcher he interviewed told him this: "My colleagues and I did a study about 10 years ago looking at the two different parties in the United States -- not in terms of ideology or policies but purely in terms of violent death rates -- and, astonishingly, we found that over a 110-year period, almost without exception, whenever there was a Republican president who was elected, the murder and suicide rates would double, and whenever there was a Democratic president elected the murder and suicide rates would halve."
