I torture myself daily by reading "Mallard Fillmore" in the Statesman. It's put on the opinion page along with "Doonesbury," the idea being to counter the supposedly liberal Doonesbury. Well, there's certainly no question that MF is conservative.
A big difference, other than the political viewpoint, is that DB has story lines and jokes that are often funny. MF is just pretty much an unrelenting series of shots at "liberals" and the Obama administration. Around Christmas time, MF ran a few strips that didn't have a political point, instead opting for a religious point, but other than that his strips are pretty similar.
And it struck me today that his strips accurately depict the Republican mindset these days. Minimal humor, zero ideas, nothing positive, just criticism after criticism, shot after shot, at their political opponents.
