A&M has a lot of conservative alumni and students, but it relies on public money, so can never be truly conservative. The faculty (outside the colleges of engineering and agriculture) has plenty of liberals.
At that point where ideology trumps education there are, I suppose, “conservative” schools. My preference would be an institution that offers all varieties of legitimate educational opportunity while at the same time reflects conservative values, in the main, among its student body and alumni. And as an Aggie grad, I can sure you that this is the case at Texas A&M, notwithstanding the presence of student organizations that exist for the advancement of progressive notions (which, by the way, are selectively present at conservative colleges as well).
