The first Democratic presidential debate will be held Tuesday, and the candidates are expected to battle it out over issues as wide-ranging as gun control, climate change, and wealth inequality in America. Here’s how the candidates are preparing for the debate:

Bernie Sanders repeatedly reminded not to point scolding finger directly into camera



Hillary Clinton and Super PAC director meeting on back-to-back park benches to hammer out last-minute details



Advisers submitting Jim Webb to a session of rapid-fire, hard-hitting questions about where he came from and why he’s here



Martin O’Malley scrambling to turn Baltimore into peaceful utopia by Tuesday night



Sanders carefully preparing to field questions about his 14-year tenure as head of Lehman Brothers



Lincoln Chafee continually reminding self he only 0.6 percent away from fourth place



Clinton put through a few warmup rounds with over-caffeinated Richard Dreyfuss



John Kerry giving Jim Webb some pointers on downplaying an accomplished military career and service in Vietnam



Stylists procuring balloon to rub against Sanders’ hair moments before debate begins
