You may have missed the lecture on liberals where we covered the fact that they are self-destructive and suicide-mongering freaks. They will see this as a positive, no matter how you say it to them.
All liberals are not alike. I used to be a pretty hard leftist, but I would not say that I was ever a self-destructive suicide-mongering freak. What turned me over to conservatism was when I myself caught some liberal lies and started wondering 'what else are they lying about'?
If any significant number of liberals are like I used to be, I have a feeling that an unprecedented number of people in this election cycle are going to take whichever color pill it is that shows reality (was it the blue one or the red one?) causing a major sea change against the Democrats.
