A leftist gay brazilian friend of mine, who is living in Germany at the moment, just was busy to vote for the OTHER candidate at the embassy last week, when we met in Germany.
Maybe this helps.
But he (my friend) is a really nice guy.
But you supply your kid with a great memory.
When it's grown up it can say:
"I saw Trump!"
And it will be proud forever.
And I remember, that I, as a rather small kid, was very excited, when my parents took me to political events.
I really enjoyed it.
I had my first camera and took pictures of a then famous german politician. I was very proud of (despite not liking that politician later in my life, lol).
Although I did not understand a word of his speech.
Don't underestimate the children!
They feel, when things are important and exciting!
(but of course be prepared for them getting tired or bored and take some games and enough food with you)-
