If you liked GJ-Bu from it's naturally base foundation which is Slice-of-Life genre and it's colorful illustration and a well maintained balance story, which doesn't have anything special particularly on plot.
Then you might like Koi To Senkyo To Chocolate (恋と選挙とチョコレート)
In Japan, participation in extra-curricular activities is as fundamental a part of an education as chalk and gym shorts. However, not all students are overachievers, and for those like Yuki Ojima, groups like the Food Research Club are welcome havens in which to slack-off. But what's a slacker to do when the radical new candidate for Student Council president announces her intent to get rid of clubs like the FRC? Well, getting the help of the current Student Council president is a good start, but HIS suggestion is so counter-intuitive that it's crazy: Yuki should run for the Student Council himself? And yet, it's SO crazy that it just might work! Especially when Chisato, the chocolate-adverse president of the FRC (and Yuki's best childhood friend,) and members of other targeted school clubs start to join the swelling FRC army. But can this army of goofs and goof-offs coast all the way to political victory? Or will someone have to step up to the plate and take one for the term?

If you liked GJ-Bu then this one might fit your preferences as well, aside from it's colorful and stunning animation, and graphics illustration. Koi To Senkyo To Chocolate has an ideal story as well. Though, GJ-Bu is a really good series, but it has some boring factors as well and Koi To Senkyo To Chocolate will remove that boring factor with a number of funny moments.
As mentioned on the synopsis, this series is all about the student council presidency election. But, it is not your just ordinary election, as it has a good plot on the side factor of the story and the comedy never leaves you.
Drama. Checked, it has a drama as well and it has a major impact as the story goes on. Comedy, drama, a significant genre that would be a crucial factor once it is combined was amazingly delivered.
