Rasmussen releases their poll on Thursday so that's my guess. It's not on their website and Drudge (and the other media outlets) may get a sneak peek.
Problem with the Rasmussen poll is that it it's an automatic poll so it can't poll cell phone users. OTOH there is a "Trump Effect" b/c of the "social desirability" bias. Try explaining to the $7.25/hr tattooed millennial pollster that 50 years ago if we had defined the words "Mexico", "illegal" and "Islam" as "race", our teachers would have covered the paper with red ink and the notation, "See Me!!!!!"
(Nice poll result in any case, hope it throws the Clintonistas into a state of panic! Maybe they'll waste even more money on ineffective ads.)
Trump is not ahead by 7%. Remember how many people thought Romney was going to win based on polls ?
