I don't remember anyone speaking of Dole, McCain, or Romney as evil. Frankly, Donald Trump has said crappier things about McCain than anyone on the Democratic side ever did. Romney did get slammed on his statement that some percentage of the population was freeloading.
CNN is as reputable a news organization as it ever was. It may well be in worse odor with the Republican base because of Trump's statements, but I don't think it was ever that popular with them. And let's face it, Fox News has a 25-year investment in depicting Hillary Clinton as bad. If we're going to talk about CNN saying bad stuff about Dole, we should probably go back and think of all the folks who pushed the notion that Hillary Clinton arranged the death of Vincent Foster.
