My brother-in-law, a really good guy, also voted for Obama. It really bothered me, as he's a very intelligent person. I just couldn't understand it.
I'm sure you and your sis can indoctrinate your nephew. I have full confidence in your ability.
Not to mention both our mom and stepmom. When my stepmom picked me up from the airport when I visited for Thanksgiving, the first topic of conversation on the drive home was the election. She says she doesn't watch or listen to anything political anymore.
However, she did say that both of my brothers are well on their way to being hard-core conservatives.
God, that joke my dad drunkenly made the other night about Matt, the 12 year old, being "made" in Hawaii... I, being rather tipsy from 3 glasses of wine, responded that "you're just like Obama, Matt." The look on his face was priceless...
Then I told him, "no one knows for sure if he was actually born there, so don't worry."
