These charts are from the recent College Reaction Poll done between September 20th through 25th of 3,633 current college students. No margin of error was given, but the poll was weighted to reflect the proper gender and racial figures of college students.
It shows that about 77% of college students are registered to vote. About 50% say they will definitely vote and another 36% say they will "maybe" vote. About 49% identify as a Democrat, while only 21% identify as Republican. About 4% say they are Libertarians, 1% identify with Green Party, and 24% say they are Independents.
They were also asked who they might support in the next presidential election. It is normally assumed by many that the vast majority would be Bernie Sanders supporters, but as the chart below shows, that is not true. He currently only has the support of about 27% of college students (one point behind Joe Biden at 28%). Trump is in third with 13%.
