DEMOCRATIC VS. REPUBLICAN GROUPS

We all know that certain groups of people tend to vote Republican and others Democratic.  The Pew Research Group has come up with a figure (see below) showing by just how much various groups tilt toward Republican or Democratic from 1992 through 2014, but to summarize, here are some results of the study:

Democrats hold advantages in party identification among blacks, Asians, Hispanics, well-educated adults and Millennials. Republicans have leads among whites – particularly white men, those with less education and evangelical Protestants – as well as members of the Silent Generation.*

A more recent study covering 1994 through 2017 shows those with no more than a high school degree shift more toward Republicans.
By contrast, white voters with no more than a high school education have moved more to the GOP over the last 10 years, though there has been little change since 2015. As recently as 2009, these voters were divided in leaned partisanship. Since then, Republicans have held significant advantages, including a 23-percentage-point lead in 2017 (58% Republican, 35% Democratic).**
I find this strange for a less educated group shift toward a political party that caters to the more wealthy (Republicans).  Elsewhere I have concluded, especially for white males with high school or less, this may be related to the Democrat's emphasis on women, minorities, and Gays who the white males feel are taking their jobs and keeping wages low.***
