Both on purpose, but also as a natural product of his viewpoint, Donald Trump works his base in the Republican Party and alt-right using politically incorrect and anti-establishment rhetoric every day. He provides constant fuel for his partisan and populist supporters.
On average, Trump is holding about two-fifths of the public’s approval. Triangulating recent polls (Fox, CNN and Gallup), he receives about 85 to 80 percent of Republicans, 35 to 30 percent of self-identified independents and less than 10 percent of Democrats. The following chart shows where he receives his 40 percent of support.
When he has slipped below 40 percent in the average, and he most recently slid to 38 percent in RealClearPolitics.com, it is mostly a reflection of small fall-offs (2 to 3 points) in each group. In addition, the percentage of Republicans has fallen in many surveys, with corresponding increases in Democrats and Independent identifiers.
A month into Trump’s presidency, he had 88 percent of Republicans, 36 percent of Independents, and for a short time, 10 percent of Democrats. Today, with his 38 percent, he has 82 percent of Republicans, 30 percent of Independents and only 7 percent of Democrats.
