Got a link for that?
Portland's 2012 murder rate was 3.3/100k. Compare that to, say, Dallas's 12.4 or Detroit's 54.6.
Dallas is leftist dominated as is, of course, Detroit. DemonRAT cities are crime-infested cesspools. Good areas are where Conservatism is triumphant such as Wasilla, AK and Branson, MO. I’m surmise that neither have much crime.
