Looks like it. I checked and they actually pulled an article by Mark Levin calling out the Conservative Treehouse as fake, so they sided with a known BS site over Mark Levin. Pretty telling.

Would have thought that about Mark Levin in the past, until he started his blatant shilling for Ted Cruz. He's lost all veneer of objectivity, he and the National Review are mouthpieces for Cruz. They have a definite agenda - so I don't think they have any more, or any less, credibility than the Conservative Treehouse and other sites that favor Trump.
Why don't we just post opinion pieces in the Blog and Opinion section and let everybody decide for themselves? I'm not real cool with a list of websites from which we are not supposed to post from. WHO makes the list? From what arbitrary checks are they judged? Some of them are blatantly obvious - and I do appreciate a list of hoax/fraud/satire sites. That is good information. But some of the other more opinion type sites should be OK to post from, as long as it's in the right category.
