Seeing as this information is coming straight from Kushner or DTJR (or whoever is managing Trump's counter-offensive), of course it's right. After all, "Trump holds all the cards - he's always held all the cards."
As to Sundance, a simple search on will return a name in seconds. Levin outed him awhile back as a Hillary supporter. I know, weird, which suggests there's something else going on behind the scenes @ CTH.
For those of us who have written reports or prepared management analyses, it's immediately obvious that Sundance's material is at a very high level. His work isn't that of some random journalist or even an experienced op-ed writer. Rather, it's a window into what Trump knows, and what Trump is doing to defeat this nation's enemies.

When do you suggest that this supposed "sundance" was a "Hillary supporter"?
