actually the kids that join the military tend to do all right in educating themselves on the vote. I just think that until the responsibility of wife kids and husband happens that most under 30 tend not to look at the big picture and get sucked into liberal ideology. give the kid some time in real world and some real world problems and they come back to non liberal thinking.
My brother is 20 years younger than me. He was a raging leftist because jobs were slim so socialism appealed to him. He got a job, paid taxes and now is a conservative for Trump. All it took for him to be a fiscal conservative was to get a good paying job.
Based on my experience the claim that the younger you are the more liberal you are is nonsense. It has to do with the socio-economic conditions one grows up in.
