I have been asked the same types of questions by my 11 year old. I wish I had the tact and self control the rest of you did.

(I'm teasing!)
I hold my tongue around my son as a general rule but I don't run from my words either. He's overheard me talking to my husband or other adults and I've always explained my frustrations in terms I think he understands. He's the "Well why?" kid. He will ask "why" until the cows come home. Like any grown up subject, I try to break it down into small bites and let him guide me. After I'm done answering, I'll say "do you want to know more?" and go from there. Above all else, we talk about how great it is that we live in a free country and that politics is a life long education. I'm still learning myself and I make a point to tell him that too.
We have talked about being a conservative v. a liberal and what that means in general terms and he has gone to the voting booth with me and watches the news with me. He gets the two party system but doesn't grasp it the way he will when he's older. He knows that we hold certain values and expect him to live by a certain code.
You guys are going to think I'm making this up. He brought this home from school and I was going to post it a long time ago. I can't make it any bigger so here's what it says:
"list two facts about this person's life" - (he put: born in 1961, has 2 daughters)
"list two important things this person has done" - (he put a big zero)
"what are two words you would use to describe this person?" - (he put: "smart (sorta)" and "good ideas")
"why should kids learn about him or her?" - (he put a big zero)
As you can see, he got a "C" and I fully supported his teacher's grading. We sat down to discuss it because he got a "B" on the McCain one - he filled that one out completely. I asked him why and he said, "because McCain is a military hero who has done a lot for our country and he seems like a good man who knows a lot and I think we need somebody as president who knows a lot. You know, like my grandpa." Okay, what about Obama? I asked and he said, "I don't know what he's done besides run for president. He seems kinda young. Isn't the president usually an old man who's been around for a long, long time? Old men are really smart and know how to do stuff like fix problems."
