Candorville: Didn't you go to Tonga, Clyde?

I know I harp on this a lot, but if you want to write a comic strip with political content, you should under no circumstances allow your political interests to overshadow your focus on your characters. Candorville, like Doonesbury, is a good comic not because of its political slant, but because its characters are recognizable and specific and funny and human.

A humorous tonal shift from time to time doesn't hurt, either.
