While most who disapprove of Trump are set in their ways, Americans who approve of Trump’s job performance are more open to the idea of changing their mind: Two-thirds (66%) say he could do something to lose their approval, while 33% say there is nothing he could do to lose their approval. Republicans (42%) are about twice as likely as independents (20%) to say there is virtually nothing Trump could do to lose their approval.
Trump has extraordinary support among several Republican subgroups who hold favorable views of his job performance. A majority (55%) of Republicans for whom Fox News is their primary news source say there is nothing Trump could do to lose their approval, compared to only 29% of Republicans who do not cite Fox News as their primary news source. Similarly, 45% of Republicans who do not have a college degree say there is virtually nothing Trump could do to lose their support, compared to 35% of college-educated Republicans who say the same.
