Rasmussen makes its cross-tabs available to its Platinum subscribers. They show Trump getting 47% of the white vote, vs. 36% for Clinton. Clinton is down one point with whites. The slight overall change is due to a Brownian Motion diminution in the black and "Other” (Rasmussen-speak for Hispanics and Asians) support for Trump. A substantial 13% percent of voters say they will vote for "some other candidate." Curiously, this includes just 12% of whites—but 20% of "Other." I wonder.
Unchanged conclusion: Trump is still not getting enough of the white vote, unquestionably because of the treasonous RATS (Republicans Against Trump). Trump could and should carry whites by at least the 60% share the GOP Congressional candidates got in 2010 and 2014. Even if you allocated the Other and No Sure vote equally, he’s still not at that level.
The polls seem to be bifurcating, with a larger number, much touted by the MSM, showing Clinton with a near-double-digit national lead. Here, I'm just going to analyze the Field poll in California: Poll: Clinton leads Trump by 30 points in California, by Lisa Hagen, July 7, 2016.
Contrary to MSM Narrative, this is not caused by a minority mutiny: the cross-tabs show Trump is only getting 37% of the white vote. (Libertarian Gary Johnston gets 14% of the white vote when factored in, and Clinton's overall lead falls to 24%. Field does not seem to poll for Green Party candidate Jill Stein).
