Go, Read: Another Editorial About The State Of Editorial Cartoons
Here. I'm surprised this discussion didn't happen during the 2012 presidential election, which I thought was an absolute wasteland for editorial cartooning and basically generated nothing memorable. There are a few from this year that I think may be recalled, as well as alt-editorial work by Tom Tomorrow and whatever we're calling what Garry Trudeau does these days.
I think articles like these are onto things when they focus on how opinions are generated rather than the craft involved with the cartoonist. People go to media to be affirmed now, not informed, and that has to make a radical difference in what cartoons are made and why.
