Voting rates have also historically varied according to age, with older Americans generally voting at higher rates than younger Americans (Figure 4). In 2016 citizens 65 years and older reported higher turnout (70.9 percent) than 45- to 64-year-olds (66.6 percent), 30- to 44-year-olds (58.7 percent) and 18- to 29-year-olds (46.1 percent).

Since 1980 18-29 year old have ranged from a low 39.6% voter turnout to a high of 52.0%. While 65 and older has ranged from 69.8% to a high of 76.1%

Figure 4 will give you the break down for the rest.

I don't blame the parents. Most kids have too many other things going on. Most worry more about how their favorite sports team are doing, having parties, going to college, working, a bunch of other things. Being young one doesn't worry too much or pay much attention to who is president or which party control congress.

It's natural.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
