By the way, this NBC/WSJ head to head showing Rubio besting Trump is the same outlier poll showing Trump losing to Cruz nationally. The only poll out of dozens of other respected survey companies showing these outlier results.
And don't get too excited that FOXNews is gleefully amplifying the outlier poll favoring Rubio. Guests to that news network who support Trump have been mysteriously absent from the guest line up for several weeks and have been, again, mysteriously replaced by guests favoring Rubio.
Murdoch will have his way.
