I agree. I think ethically corrupt would be more accurate. 

It may have been one person's tongue and check comment but every article about Palin, which this one shouldn't have been. The only one that should care about Palin's facebook post's are Palin's followers. A journalist for the WaPo shouldn't be making a story about it . He could have quite easily made his point without conjuring Trump nor Palin. 

Then I think you don't know what credibility is.  You equate agreement with credibility.  There are many on the Anthropomorphic Climate Change ( The climate is ALWAYS changing and few deny that)  side that have lost credibility because they fudged the data, or want to prosecute those that dissent.  That is a  issue of credibility, not disagreement.

 I think the vast majority of the Britions are relatively ignorant to Palin. The widespread hatred of her is an American Liberal phenomenon.  It would have had no bearing on their election.
