Pew Research Center
The balance of leaned partisan affiliation among the public has changed little in recent years: 48% identify with the Democratic Party or lean Democratic, while 39% identify as Republicans or lean toward the GOP. Since 1992, only once – in 2002 – have as many people leaned toward the Republican Party as the Democratic Party (43% each). They crossed over two times, one in 2002 as stated and once in 1994 (44% R, 44% D).

Education
Democrats now hold a 12-point lead (52% to 40%) in leaned party identification among those with at least a college degree, up from just a four point gap seen as recently as 2010 (48% to 44%). Much of this advantage has come among adults with post-graduate experience; currently, 56% lean Democratic while just 36% lean Republican. Among those who have received a college degree but have no post-graduate experience, the gap is much narrower: 48% identify as Democrats or lean Democratic, while 43% affiliate with the GOP or lean Republican.

Pew Research Center
Religious Tradition
Republicans have widened their lead in leaned party identification among white evangelical Protestants: About two-thirds (68%) of white evangelicals lean Republican, while just 22% lean Democratic. The GOP also holds a substantial advantage among Mormons. Fully 70% of Mormons lean Republican, while just 22% lean Democratic.
The partisan leanings of white mainline Protestants and white Catholics mirror those of all whites. Jews remain a solidly Democratic group: Nearly twice as many lean Democratic (61%) as Republican (31%). People with no religious affiliation increasingly lean toward the Democratic Party. Currently, 61% of those who do not identify with any religion lean Democratic – a 22-year high. Back to top
