Within the US young, college aged, individuals are commonly thought of being more attracted to the democratic party, while it's also commonly believed that the elderly usually vote republican. I believe studies have backed these general archetypes up by showing that Democrats tend to see a larger percentage of the college-age demographic, and elderly shown to significantly favor republican candidates.
However, it seems to me when I meet people, particularly the ones that regularly vote and associate themselves with either party, they seem to be pretty adamant about the party as a whole. It's hard for me to imagine them changing political parties; for that matter I suspect many voters don't even know how to actually change which party they are registered to.
I'm wondering if the statistics showing the young favor a different party then they old imply that people (on average) tend to adjust which party they lean towards over the course of their age? Or is the discrepancy due to some other statistical trends. For instance do democratically inclined voters tending to stop voting as they age and Republican inclined voters tending to start voting more as they age. Ie people stick to the same party and all that changes is their tendency to vote.
