Why the Dems want free tuition
Let's face it. This is not about social justice. The Dems are trying to stack the election process for the future. That obviously explains the influx of Hispanics. So while the number of Hispanics that are registered Dems has declined as proportion of the population the number of "dem-leaning" Hispanics has increased. Similarly for "college educated voters". College education is almost totally liberal/progressive. The Dems feel that the longer they can keep someone in school regardless of the fact that these kids aren't learning useful skillsets, that they'll vote Dem. Similarly the elimination of religion continues to move voters toward the Dems. So the more atheists the more Dems
