How will he explain this act of selfishness to his kids when they are old enough to understand?
Exactly, he’s depriving his kids of their grandpa. How hard would it be to say, “Kids, Gramps is voting for Trump and I don’t agree, but he’s your grandpa and we will respect him and we will keep visiting him, because sometimes people disagree”? No, leftists are too intolerant and hateful for that. Unfortunately, the grandpa as no rights in this case and the brat can keep his grandkids from him. I hope someday the kids turn against their rotten dad and reunite with the grandpa.
