Well, I can't get that particular video to work,
but here's one
and a different one
I'm not sure what I can specifically say about kids or kids + parents making You Tube videos about politics. I don't see how it's any different from making videos about anything else, and I don't think there is anything wrong with kids being enthusiastic either about their own or their parent's political ideals.
I found some pretty creepy ones with a quick search, but it wasn't the politics that was terrible, and that's You-Tube for you.
What about kids being indoctrinated by their parents (morals teaching, church, ect.) is communist or socialist? Parents are EXPECTED to tell their kids what they think is right or wrong.
