Day by Day (also Day by Day Cartoon) is an American political webcomic by Chris Muir. The humor usually centers on four principal characters who had initially been presented as co-workers at an unspecified firm until the firm went out of business on December 25, 2007. Romantic relationships among the principals resulted in marriages and children, with one of the couples opening a small bar in the unnamed Texas Rio Grande Valley ranchland in which the strip is now principally set. These characters, their friends, and their families remain the strip's focus. The strip has a conservative libertarian viewpoint, and often makes reference to political weblogs. It was a Yahoo! Pick in the "Comics and Animation" category in 2004.
